PG7601 Piston Gauge

sku Product SKU:  FCL-PG7601

PG7000 PISTON GAUGE LINE FEATURES REFERENCE LEVEL PRESSURE STANDARDS OFFERING A UNIFIED SOLUTION FROM VACUUM TO 500 MPA

  • State-of-the-art primary pressure standards for the lowest uncertainty levels
  • Unified solution from vacuum to 500 MPa
  • Outputs fully validated reference pressures in real time
  • Intuitive local operator interface
  • Manual, semi-automated and fully automated configurations

The PG7000 Series calibration standards are based on the fundamental principle of mass loaded onto a piston to apply a known force to a known effective area

Integrated piston-cylinder modules
Each PG7000 piston-cylinder is an integrated metrological assembly that includes the critical piston-cylinder mounting components. All of the mechanical parts that affect piston cylinder metrology are associated with the individual piston-cylinder, rather than being common parts of the piston gauge platform, enabling the user to:

  • Change ranges (piston-cylinders) in seconds, without using tools.
  • Handle and interchange piston-cylinders without exposing critical surfaces to contamination.
  • Protect the piston-cylinder from damage due to accidental shock or impact when handling.
  • Improve measurement reproducibility by avoiding frequent assembly/disassembly of mounting components.
  • Improve piston-cylinder mounting design by allowing each mounting system to be optimized for a piston-cylinder size and range.

Mass loading concentricity
The number of independent parts between the piston and mass load has been reduced to two—the piston cap and the mass loading bell. The piston head is effectively made part of the piston by machining it after installation concentrically to the piston within ± 20 microns.

Integrated electronics, software and remote interfacing
The electronics for monitoring all ambient and instrument conditions and functions are integrated into the PG7000 platform. RS-232 and IEEE 488 interfaces are included for remote communication. The system power supplies are also contained in the terminal to remove their heat source from the PG platform. For local operation, the user interacts with the PG7000 through a keypad and alphanumeric display on a compact terminal, allowing rapid, intuitive operation.

On-board measurement of operating conditions
PG7000 includes integrated on-board measurement of all the ambient and operating conditions needed to calculate pressure within tolerance, including relative humidity, barometric pressure, ambient temperature, piston-cylinder temperature, and reference vacuum. Individual measurements can be observed in real time, both locally through the PG terminal and remotely over the RS-232 or IEEE 488 interface. Verification and recalibration of the on-board sensors is supported by embedded software.

Monitoring piston behavior
PG7000 measures and provides real time indication of piston position, drop rate, rotation rate, and rotation decelaration. Piston position is measured on the LVDT principle, with a ring on the inside of the mass loading bell acting as the armature. Rotation rate is measured optically by a sensor in the mounting post, which detects the movement of a notched ring on the inside of the mass loading bell. Both measurement systems are completely non-interfering, with no influence on the free movement of the piston in any axis.

Ready/not ready indication
The “ready/not ready" indication provides the operator with a clear “go/no go" indication of when an in-tolerance measurement can be made. It is based on testing for a variety of operating conditions, including piston position, piston fall rate, piston rotation rate, piston rotation deceleration, piston temperature rate of change and vacuum reference (when applicable). A ready condition is indicated when all conditions fall within specific limits. The limits for the various ready/not ready criteria can be customized by the user if desired.

Piston near-float detection
One of the most tedious aspects of operating a conventional piston gauge is adjusting pressure to float the piston. The piston lifts suddenly and without warning at the exact pressure corresponding to the mass loaded on the piston. Finding that point without overshooting requires slow and cautious pressure control. PG7000 makes it easier to float the piston with a piston preloading system, which provides advance warning that the pressure is near the point where the piston will leave end of stroke. The preloading system only affects the piston when it is at end of stroke; it does not interfere with the free movement of the piston when it is floating.

Intelligent piston rotation
PG7000 is the first commercially available piston gauge to provide monitoring of rotation rate and decay in rotation rate. These measurements are used to assure that pressure readings are always made within limits. This relieves the operator of rotation rate monitoring responsibility and replaces subjective operator judgment with objective measurement.

Storage and shipping containers
The PG7000 piston gauge platform and mass set are packaged in heavy duty, weather proof, molded transit cases with custom inserts to provide optimum protection. PG7000 piston-cylinders modules are delivered in compact, virtually indestructible PVC bullet cases.

Advanced pressure generation and control components
All PG7000 pressure accessories are designed to increase the efficiency and ergonomics of piston gauge operation. These include manual, semi-automated and fully automated options to quickly and easily generate pressure and float the piston at the set point.

COMPASS® for Pressure calibration assistance software
COMPASS software sets up records for the units under test (UUT), defines and associates test procedures with UUTs, runs tests, acquires reference and test data, produces standard and custom calibration reports. All reference, UUT and test data is collected and stored in a database and standard delimited files. COMPASS can manage any kind of test from manual operator control and logging of test data to fully automated, unattended test execution.

A unified solution from vacuum to 500 MPa
The PG7000 line of piston gauges covers the complete range of pressure from very low absolute and differential in gas, up to 500 MPa (75 000 psi) in oil. While several piston gauge platforms and specialized accessories may be needed to cover different ranges and media, a consistent user interface and operational principles are maintained throughout the line. In most cases, complete gas and oil calibration capability can be achieved with just two PG platforms, four piston-cylinder modules and one mass set. Maintaining consistency from system to system makes them easier to learn and to use. Maintenance costs are reduced by minimizing the number of metrological elements to be supported.

PG7000 Piston Cylinder Modules
The piston-cylinder defines effective area and is the piston gauge’s principal metrological element. The piston-cylinder’s intrinsic characteristics and how it is mounted and exploited are the keys to piston gauge performance.

PG7000 piston-cylinders are manufactured by Fluke Calibration using proprietary production techniques that result in pistons and cylinders whose typical shape is within less than 0.2 micron from ideal geometry.

Pure gas operated piston-cylinders use large diameters and very small annular gaps to minimize gas species and operating mode effects and to maximize piston float times. For example, the typical annular gap of a 35 mm gas operated piston-cylinder is less than 1 micron. Oil operated piston-cylinders use small diameters to reduce the quantity of mass needed to cover the typical high pressure range.

All Type 7000 pistons and cylinders are made of tungsten carbide. Each PG7000 piston-cylinder is a complete, integrated metrological assembly that includes the critical piston-cylinder mounting components for improved metrological performance. All Type 7000 piston-cylinders use free deformation mounting systems in which the cylinder is allowed to deform under the influence of applied pressure, without O-rings or seals along the cylinder length. For higher pressure gas assemblies, a new mounting system, negative free deformation, applies the measured pressure uniformly along the full length of the cylinder. This reduces deformation under pressure, so piston drop rates remain low even at high operating pressures, while avoiding the unpredictable strain points of conventional reentrant designs.

PG7000 Mass Sets
Masses loaded on the piston are accelerated by gravity to apply a known force on the piston against which the defined pressure is balanced.

A PG7000 manual mass set is made up of main masses of 10 kg or 5 kg, fractionary masses in 5-2-2-1 progression from 0.5 kg to 0.1 kg, and a trim mass set with masses from 50 kg to 0.01 g. Any desired mass value within the mass set range can be loaded to 0.01 g. All main and fractionary masses are machined from solid, nonmagnetic stainless steel and adjusted to their nominal values in the mass without cavities or trimming hardware which can reduce mass stability over time. Individual masses are comfortable to handle, with angled lifting surfaces on the edge of each mass and special mass trays that assist in orderly loading and unloading.

A PG7000 automated mass set is composed of main mass discs of 6.2 or 10 kg each and a set of tubular masses in binary progression from 0.1 to 3.2 or 6.4 kg.

A pneumatically driven automated mass handling accessory (AMH) loads requested mass values in increments of 0.1 kg. The AMH and mass set are easily removed to access the piston-cylinder module when necessary.

1560 Black Stack Thermometer Readout

sku Product SKU:  FCL-1560

The 1560 Black Stack thermometer readout can be any kind of thermometer you want it to be, and it works in three distinctive ways.

It’s a reference thermometer with a NIST traceable calibration; it’s an automated calibration system reading your reference probe and sensors you’re testing; or it’s a high-accuracy data acquisition system. And it does each of these functions better than any other thermometer currently on the market.

The Stack consists of up to eight different modules that fit together to do any type of thermometry you choose. You can buy all of them, or any combination of them, and change the Stack and its functions anytime you want. Each module stacks behind the preceding one, and when you add a module, the Stack’s software automatically reconfigures itself to include all of the new functions supplied by that module. There’s nothing to take apart. No boards need to be installed. There’s no software to load, and nothing has to be calibrated. Just stack a new module onto the back of the previous modules and you’re ready to use the Black Stack and all of its remarkable features.

Fluke Calibration’s new Model 9935 Multi Channel LogWare makes the Black Stack an even more powerful data acquisition tool. LogWare provides graphical and statistical analysis of each channel you’re measuring (up to 96 with the Black Stack). And with alarms that can be customized, delayed start times, and selectable logging intervals, LogWare turns the Black Stack into the most powerful temperature data acquisition tool on the market.

THE BASE UNIT

The Stack starts with a base module. It consists of two parts: a display with the main processor and a power supply. The base module supplies power, communication management, and software coordination for all of the other modules. It has the display, control buttons, and RS-232 port built-in.

Each base module can handle eight thermometer modules stacked behind it with a maximum of 96 sensor inputs. The base module never needs calibration and performs its own diagnostic self-test each time it powers up. The thermometer characteristics of each base module are defined by the thermometry modules stacked behind it.

THE MODULES

There are nine thermometry modules: an SPRT module, a high-temp PRT module, a PRT scanner module, a standards thermistor module, two 1000-ohm PRT modules, a thermistor scanner module, a precision thermocouple module, and a thermocouple scanner module.

Each module has its own processor and connects to the stack on a proprietary digital bus. Each retains its own calibration data and performs all analog measurement functions within the module.

SPRT MODULE 2560

The SPRT module reads 25-ohm and 100-ohm four-wire RTDs, PRTs, and SPRTs with very high accuracy. It turns the Stack into a first-rate reference thermometer with an accuracy to ±0.005°C.

 

It has two input channels so you can collect data with two reference sensors, or you can do comparison calibrations of one sensor against a calibrated reference sensor.

Temperature conversion features include direct resistance measurement, ITS-90, W(T90), IPTS-68, Callendar-Van Dusen, or an RTD polynomial conversion. The user-changeable default values for the CVD conversion fit the 100-ohm, 0.00385 ALPHA sensor described by IEC-751.

The SPRT modules can be used one at a time or combined together in any combination for reading up to 16 different reference thermometers. If you stack an SPRT module with a scanner module, you can test multiple sensors against your reference. Unlike other competitive instruments, our PRT Scanner Module operates with or without the two-channel SPRT module. If you can think of a way to use a reference thermometer, you can do it with the Stack.

HIGH-TEMP PRT MODULE 2561

This module reads 2.5-ohm and 0.25-ohm four-wire HTPRTs and RTDs. The complete resistance range covers up to 5-ohm sensors with applications as high as 1200°C. The temperature conversion features are the same as for the SPRT module, and like the SPRT module, the connectors are gold plated.

PRT SCANNER 2562

This module reads eight channels of two-, three- or four-wire 100-ohm PRTs or RTDs. The accuracy is ±0.01°C at 0°C for calibration of industrial sensors. The common industrial RTD can be read with the default values in the CVD temperature conversion for fast setup of industrial applications, or you can enter individual probe constants for higher accuracy data acquisition.

1000-OHM PRT MODULES 2567 AND 2568

For 1000-ohm PRTs, these modules provide all the same great features as the 2560 and 2562 Modules. The two-channel 2567 Module has a resistance range of 0 to 4000 ohms and is accurate to ±0.006°C at 0°C. The 2568 Module reads up to eight 1000-ohm PRTs and at 0°C is accurate to ±0.01°C. Don’t use an ohmmeter or multimeter to read your 1000-ohm PRTs when you can use a Black Stack loaded with convenient temperature functions.

STANDARDS THERMISTOR MODULE 2563

Special low-drift thermistors are becoming increasingly popular as reference probes in applications with modest temperature ranges up to 100°C. This module has a temperature accuracy of ±0.0013°C at 0°C with a resolution of 0.0001°C.

The 2563 Thermistor Module has two input channels. It displays direct resistance in ohms or converts directly to a temperature readout using either the Steinhart-Hart equation or a higher-order polynomial.

THERMISTOR SCANNER MODULE 2564

This module is usable with any type of thermistor but has eight channels instead of the two channels found on the Standards Thermistor Module and operates with or without the Standards Thermistor Module. This module’s accuracy is ±0.0025°C at 0°C for all eight channels.

The eight channels make the 2564 module an excellent data acquisition tool. It can be used in research work or for verification of biomedical equipment such as DNA sequencing apparatus.

PRECISION THERMOCOUPLE MODULE 2565

This precision thermocouple module reads any type of thermocouple, including type S platinum thermocouples and the new gold-platinum thermocouples for standards work. This two-channel module has internal cold junction compensation, or you can use an external source for even greater accuracy.

All the standard ANSI thermocouple types are preprogrammed; however, you can choose a conversion method and then enter the probe characteristics of your sensor, creating a system-calibrated channel. The 2565 module accepts up to three calibration points for error adjustment in the individual sensor. A polynomial interpolation function calculates the points between your measurements.

Type R, type S, and gold-platinum conversions accept complete polynomial calibration coefficients. Additionally, a thermocouple conversion function calculates temperature by interpolating from a table. You enter the temperature in degrees C and the corresponding voltage for your specific sensor from 1 to 10 temperatures. Interpolation is performed between the entered points.

THERMOCOUPLE SCANNER MODULE 2566

This module has 12 channels and reads K, J, T, S, R, B, E, and N thermocouples. Each channel can be set to read a different type of thermocouple. All temperature readings are performed in exactly the same manner as with the 2565 module.

The connectors on the scanner module are special dual connectors that accept both the common miniature and standard thermocouple connectors. If you want to use screw terminals, use the appropriately-sized connector with the hood removed.

FEATURES COMMON TO ALL MODULES

The 1560 Black Stack is an incredible thermometer. You buy only the modules you need for the work you are doing. If your work changes, simply order the modules with the functions you need and slip them onto the back of the Stack. Your thermometer changes its software, display, and method of operation to match the new functions you’ve added.

Remember, you never have to open the case to add modules. There’s no software to load. It’s all automatic.

Each module stores its own calibration internally, so you can add or change modules without recalibrating the whole stack. Module calibration is digital and is performed manually through the base’s front panel or over the RS-232 link. If your lab has the capability, you can calibrate modules yourself. If not, send them to us with or without your base unit and we’ll recalibrate them.

The LCD screen has multiple methods of displaying data, including a graphical strip chart recorder. The graphical capability of the Black Stack makes testing temperature stability easier than ever. Vertical scaling and graph resolution are automatic.

The Stack has high-accuracy, two-channel capability or multi-channel functionality if you need it. Its memory stores the most recent 1000 readings, or you can send your data to your PC through the RS-232 port. Each data point is time and date stamped. An IEEE-488 port is optional.

With the Black Stack you can read data almost anyway you like—in ohms, millivolts, or temperature, according to your application and preference.

Remember, this thermometer’s calibration is traceable to NIST. Its accuracy is as high as ±0.0013°C, depending on the module and sensor you’re using.

HEY! WHY DID YOU MAKE IT LOOK LIKE THAT?!

We get asked this question more than any other question. There are several reasons for the shape of the Black Stack.

 

When we started the design process on the Black Stack, we wanted a unique instrument that was a true technological leap in thermometry. Incremental improvements are okay sometimes, but if you’re going to lead the industry, you might as well go out and lead it.

Here are some of the design criteria we started with. The new thermometer had to be capable of transforming itself into any kind of thermometry instrument the customer wanted, and it had to do this without having to open the box, replace boards or set up anything. All connections must be easily accessible from the front of the instrument, with no connectors on the front panel. The front panel had to be easy to read, all features including programming should be done on the front panel and the programming should take advantage of the graphical capability of the display. The software had to be as creative and as versatile as the instrument. It had to be easy to use and, if at all possible, even fun to use. And finally, it had to be very accurate.

The shape of the Black Stack facilitates the function and usability of the instrument. And it is unbelievably functional and fun to use.

The only way you’ll truly understand what we’re talking about is to get one and try it. Hundreds of customers, including many national standards labs, already have it!

molstic-L Mounting Systems

sku Product SKU:  FCL-molstic-L

molstics provide a quick connector input for convenient connection to the gas supply. This is followed by a 2 micron (0.5 micron for low flow) filter to protect the downstream components. Then, an adjustable regulator sets and regulates optimum molbloc upstream pressure and protects the molbox transducers against accidental overpressure. The regulator range supports all standard molbloc operating pressure ranges. A bellows shut-off valve, just before the molbloc, allows the gas supply to be shut-off for configuration changes and/or system leak checking.

Special cradles support the molbloc(s). A connection and pads are provided downstream of the molbloc for mounting the MFC (mass flow controller), another device under test, or the optional metering valve kit for manual flow control.

Single channel molstics are available to accommodate single molblocs. Dual channel models allow two molblocs to be mounted simultaneously to switch between two different molbloc ranges without changing hardware or to take advantage of molbox1+'s capability to run two molblocs in parallel.

There are low, mid and high flow versions of molstic. Low flow molstics use a unique, very high stability pressure regulator and minimize dead volumes. They are required for effective use of 2E2-L and lower molblocs and can be used up to the 1E3-L molbloc size. The mid flow molstics cover the ranges of all the molblocs from as low 2E2-L up to the 3E4-L. The high flow molstic is required for the 1E5-L (100 slm) molbloc and supports that molbloc only.

sku Product SKU:  FCL-molstic-S

A key benefit of its modular design is that molstic-S can be used for testing devices in either the upstream or downstream position. The optional, adjustable DUT stand (P/N 401934) accommodates large DUTs that do not fit on the molstic-S.

molstic-S is available in either 1/2 inch or 1/4 inch system plumbing sizes. The 1/4 inch size is dedicated to the molbloc-S elements designated 1E2-S and lower, and the 1/2 inch size is for the 2E2-S through 2E3-S elements. All molstic-S platforms come with integrated flow shut-off/metering valves. This allows for system leak testing and provides a means of flow control (if required by DUT type). Optional high resolution metering valve kits are available for use with the 1/4 inch molstic-S in order to obtain finer flow control capability.

MOLSTIC-S USAGE

Because molbloc-S operates in the critical flow regime, test devices that have flow control capability must be installed upstream of the molbloc-S in order to control flow.

Devices that are to be calibrated at atmospheric pressure are generally installed downstream of the molbloc-S. molstic-S is built modularly in order to provide this flexibility.

Inlet gas supply pressure regulation is vitally important in order to protect the molbox pressure transducers. Therefore, it is recommended that the molstic-S Supply Only molstic be used upstream of test devices that have flow control capability and that the pressure reducing regulator option be installed on the molstic-S when calibrating devices that operate at atmospheric pressure. An optional back pressure regulator can be installed on the molstic-S to provide control of an upstream DUTs downstream pressure.

molstic-S™ provides an engineered solution to the practical issues of mounting molbloc-S® mass flow elements, connecting a gas supply, regulating the operating pressure and connecting the device under test (DUT). A filter is included on the 1/4 inch molstic-S to protect the smaller molbloc-S elements from contamination. Highest quality components are integrated into a convenient, compact, modular assembly to assure optimum molbloc®/molbox™ performance.

The single channel molstic-S is designed to accommodate one molbloc-S element. The dual channel allows two molbloc-S elements to be simultaneously mounted, allowing use of two ranges without changing hardware during a test. In addition, the outlet of the two molbloc-S elements can be plumbed in parallel using the downstream tee assembly (P/N 401884) in order to obtain additional flow range capacity when using a two-channel molbox1+.

5615 Secondary Reference Temperature Standards

sku Product SKU:  FCL-5615

The 5615-12 is a Platinum Resistance Thermometer (PRT) with an Inconel™ 600 sheath that’s 305 mm (12 in) long and 6.35 mm (0.250 in) in diameter. It is a secondary reference temperature standard designed to bridge the gap between the highest laboratory standards and industrial or second-tier lab locations. It has accuracy of ± 0.012 °C at 0.01 °C.

The element is constructed of reference-grade platinum wire (99.999 % pure) for excellent stability. The wire is wound in a coil and placed in a mandrel where it’s uniformly supported in a manner that virtually eliminates hysteresis. The electrical configuration is a four-wire current-potential hookup that eliminate the effects of lead-wire resistance.

These Inconel™-sheathed probes have a fully supported sensing element, making them more durable than SPRTs. The element is protected in an ultrahigh-purity ceramic case with a hermetic glass seal to improve output stability by locking out moisture and contaminants.

This probe comes calibrated with ITS-90 coefficients, making it compatible with many excellent readout devices, including Fluke Calibration’s 1529 Chub-E4, 1560 Black Stack, and 1502A Tweener. It bridges the gap between a 100-ohm industrial RTD and an SPRT.

For those needing faster thermal response, or where diameter and immersion depth are problems, order the 5615-9 or 5615-6. These probes are excellent reference probes for comparison calibrations in a Fluke Calibration dry-well. The sheaths of the 5615-6 and 5615-9 are 4.76 mm (0.188 in) in diameter.

A printout of sensor resistance is provided in 1 °C increments for each probe. The 5615-9 and 5615-12 are calibrated from –196 °C to 420 °C. The 5615-6 is calibrated to 300 °C.

We’ve tested many of the probes on the market. We’ve used them in our manufacturing facility and tested them in the lab, and this is an excellent secondary standards PRT. Other instruments on the market are priced much higher, have lower stability, or are of lower quality.

Remember, these are reliable instruments and each probe comes with its own individual NVLAP-accredited calibration, lab code 200706-0.

  • Affordable wide-range accuracy
  • Calibrated accuracy ± 0.012 °C at 0 °C
  • Reference-grade platinum sensing element
  • NVLAP-accredited calibration included, lab code 200706-0

For years, you’ve relied on our 5612, 5613, and 5614 Secondary Reference Probes. These field-durable, lab-accurate PRTs have been replaced by the 5615, which comes with a NVLAP accredited calibration.

IET-PRS-370

PRS-370 Self-Adjusting Programmable Resistance Box & RTD Simulator

sku Product SKU:  IET-PRS-370

The PRS-370 is a Self-Adjusting Programmable Resistance Substituter, just connect an 8.5 digit DMM; Fluke 8508A, 8588A or the Keysight 3458A to the PRS-370 via the IEEE-488 interface, and the PRS-370 becomes a short-term stable variable standard of resistance.

The PRS-370 instructs the DMM to make a measurement of the source resistance and then automatically fine adjusts the output resistance to achieve the "best" accuracy to the nominal resistance value, typically better than 10 ppm.

The PRS-370 utilizes both the front and rear binding posts so that the DUT and DMM can be connected at the same time. Once the resistance measurement is complete using the DMM and rear binding posts, the source resistance is switched to the front binding posts.

The large graphical color display shows the target resistance, ∆ from nominal, measured resistance from the DMM and measurement uncertainty of the DMM.



Save time in adjustment
At the touch of a button the built-in firmware routine allows for automatic calibration of the internal resistors by just connecting a DMM to the PRS-370 . No entering values or manual trimming saves significant time over traditional programmable resistance decades or manual decades.

The right mix of features
The PRS-370 was designed with the right mix of features for to be efficient for both manual and automated application in both laboratory and production environments. With its wide range the PRS-370 was designed to replace multiple decade boxes, individual resistance standards and reduce test time.

User interface
The PRS-370 utilizes a large state-of-the-art color capacitive touchscreen which provides super fast response time. Even in low or bright light conditions the display provides exceptional clarity with large fonts and easy-to-read menus.

The user interface makes the PRS-370 well suited for high accuracy requirements for both manual and automated applications such as; calibration of resistance meters, calibration of temperature controllers and indicators, automated test systems requiring a precision resistive load

The user interface also features softkeys and a numeric keypad allowing use of the user interface without using the touch-screen.

No zero resistance
The PRS Series programmable resistance box employs very low resistance, low thermal emf relays with gold-clad silver-alloy contacts. A special design keeps contact resistance to a minimum. The gold plating keeps the silver contacts from becoming tarnished when unused, or when only low currents are passed through them. This is most often the case when only minute test currents are drawn by digital multimeters and other test instruments. Contact resistance remains low and repeatable through the use of multiple contacts.

Highest quality components
The programmable resistance box employs, high-quality gold-plated tellurium-copper five-way binding posts serve to minimize the thermal emf effects, which would produce errors in dc resistance measurements. Resistors are custom Z-foil and low inductance wirewound for low TC and excellent stability.

5 year warranty
With its industry leading 5 year warranty all aspects of the PRS-370 focus on reliability, reduced ownership costs and simplicity out of the box.

RTD calibration
The PRS-370 is also a programmable decade resistor and RTD simulator that can be used stand-alone to automate your source resistance and temperature controller testing.
Built-in tables for PT100 and PT1000 RTDs and direct resistance substitution makes the PRS-370 ideal for for RTD (Resistance Temperature Detector) simulation. User defined tables can also be created for use with other RTDs. The operator can enter temperature directly and the correct resistance will automatically be programmed.

Resistor carousel
Built-in EIA "preferred value" resistance tables of 1% (E96), 5% (E24), 10% (E12) increments or user specified increment allows the PRS-370 to be used as a resistor carousel.

AC performance
The PRS-370 programmable resistance box is a precision resistance source with excellent characteristics of stability, temperature coefficient, and power coefficient. The use of low inductance wirewound and Z-foil resistors allows the PRS-370 to be used in ac applications with minimal resistance change below 1 kHz.

Interface
Operation is both local using a color touch screen and numeric keypad or remote control with the standard IEEE-488 interface. The versatility of the IEEE-488 interface allows you to completely automate your testing when not used with a DMM.

Calibration history
Calibration history of each internal resistor can be reviewed to show drift and performance. The calibration history data can be retrieved via SCPI command for further analysis.
Pressing a switch on the front panel allows access to calibration history and adjustment menus minimizing unauthorized access.
