Product DescriptionGeneral information:
SXGZ-B Insulation Resistance Meter Calibrator is the reference instrument to calibrate insulation resistance meter. The resistance output maximum limitation is 20G, nominal working voltage is 3kV, maximum measuring voltage is 3.5kV, input impedance 5G. It's suitable for all models pointer type insulation resistance meter.
Features:
Designed with independent leakage shield terminal and ground terminal, no obvious unstable, short circuit and open circuit.
High performance switch, long life service.
The open circuit voltage, mid-value voltage and peak value voltage are all measurable.
