GZX92 type high voltage and high resistance box

1. Overview
The high-voltage and high-resistance box is developed and produced in accordance with relevant documents such as the Insulation Resistance Meter (Megohmmeter) Verification Regulations and the DC Resistor Verification Regulations. The device is designed with independent leakage shielding terminals and grounding terminals to fully meet the requirements of the - Insulation Resistance Meter Verification Regulations and - DC Resistor Verification Regulations. It can not only be used to calibrate various types of pointer insulation resistance meters, but can also be used as a standard for calibrating digital insulation resistance meters, insulation resistance testers, and as a DC standard high-value resistor. It has a long technical life and mechanical life.
