Continuously variable high voltage resistance outputs source high-ohms, high voltage resistors to enable calibration of insulation resistance testers/megohmmeters up to 5 kV. The continuously variable feature lets the user set any resistance value to match the device under test (DUT) requirement and adjust the 5322A output to a nominal value, which aids in calibrating older-style hand-cranked testers.
Active Loop Compensation makes it easier to calibrate the loop/line impedance function of an installation tester by canceling residual line impedance during calibrations.
600 V source (VLC option) allows calibration of ac voltage measurements on workloads with measurement capabilities. This feature is also useful for powering many types of PAT testers.
4-wire low resistance sources enable precision low current measurements and high current ground bond measurements, providing accuracy for testing newer 4-wire testers.
Optional 5322A-LOAD 5 kV high voltage load resistors include paralleling capability for precision hipot testing.
RCD simulation enables testing of installation and PAT testers with excellent time and current level accuracy. 5322A trip times provide better than 4:1 test uncertainty ratios with 1 % trip current uncertainty.
Ripple coefficient and THD measurements display hipot testers' signal purity measurements to 5 kV as required by many regulations.
Multiple models give you the flexibility to select the capabilities best suited to your workload and budget.
MET/CAL software compatibility automates the 5322A in 5320A emulation mode for improved throughput and greater consistency.
