-short circuit loop impedance measurement in networks with nominal voltage: 220/380V, 230/400V, 240/415V,

with frequency 45…65Hz;

- short circuit loop impedance measurement with 15mA current, without triggering RCD.

Detection of the replacement L and N in the socket and automatic in the meter.

Low voltage resistance measurement of protective circuits and junctions:

- measurement of resistance with ±200mA current,

- calibration of test leads – possibility of using any length of test leads,

- low current resistance measurement with acoustic signaling.

Rapid check for the correct connection of PE wire using touch electrode.

Measurement of mains voltage and frequency.

Power supply from LR6 batteries or NiMH accumulators (option).

The device meets the requirements of IEC 61557 standard.
