Summary:
GZX92C high voltage and high resistance box is developed and produced according to the verification regulations of jjg622-97 insulation resistance meter (megohm meter), jjg690-2000 insulation resistance meter (high resistance meter) and jjg166-93 dc resistor.
The device has an independent leakage shielding end button, no obvious instability and short circuit, open circuit phenomenon in the measurement process, can be used as a verification of various types of pointer megohm meter and digital megohm meter. In order to broaden the scope of use, the device is designed to meet the need of verification of high resistance meter.
