Description

The MZC-310S is a professional portable meter for testing electrical installations with over-current circuit breakers. The instrument measures short circuit L-PE, L-N and L-L loop impedance and prospective short circuit loop current. Measurements can be done either with low measurement current (up to 42A) with 2-pole method or high measurement current (up to 280A) with 4-pole method that enables measurements with very high accuracy and resolution. The results can be stored in the internal memory and send to a computer via serial interface.
