Possible measurements

Short-circuit loop measurement:
*impedance measurement with 23 A current (44 A phase-to-phase) - short-circuit resistor R=10,
*measurement range: 95...440 V, frequency 45...65 Hz,

Short-circuit loop measurement with resolution 0,01, in distribution network without tiggering RCD (In30 mA):
*automatic calculation of short-circuit, detection of phase voltage and phase-to-phase voltage,
*additional UNI-Schuko plug for automatic measurement, AGT adapter for 3 phase network measurement.

Testing of general and selective RCD with the rated differential current of 10,30,100,300,500 and 1000 mA. (Type AC, A and B).

Measurement of insulation resistance:
*with test voltage 250 V, 500 V, 1000 V, 2500 V,
*measurement range up to 10G,
