Test Function Specifications
The operational error specification reference for digit counts is defined as ±(% of reading + digit counts). The operational error for other specifications that reference a percentage is defined as the percentage of the reading, unless otherwise specified. The operational error specification reference temperature for all readings is 23 °C ±5K, with a temperature coefficient of 0.1 %/°C.

Electromagnetic Compatibility (EMC)
International Standards
- IEC 61326-1: Basic Electromagnetic Environment
- CISPR 11: Group 1, Class A
Group 1: This equipment intentionally generates and/or uses conductively coupled radio frequency energy, which is essential for its internal function.
Class A: This equipment is suitable for use in all establishments except domestic environments and those directly connected to a low-voltage power supply network that serves residential buildings. Due to conducted and radiated disturbances, ensuring electromagnetic compatibility in other environments may be challenging.
⚠️ Caution: This equipment is not intended for use in residential environments and may not provide adequate protection against radio interference in such settings. When connected to a test object, emissions exceeding the levels required by CISPR 11 may occur.
Korea (KCC) – Class A Equipment (Industrial Broadcasting & Communication Equipment)
Class A: This equipment meets the requirements for industrial electromagnetic wave equipment, and the seller or user should take note of this. It is intended for use in business environments and must not be used in homes.
