The most important features of AMZC-310S are:

Measurement of very low short circuit loop impedances (with resolution 0,1mΩ) with a current of 150A at 230V; maximum 280A at 440V or measurement with a current of 23A at 230V; maximum 42A at 440V:

  • Measurements in installations with rated voltages between: 220/380V and 230/400V and frequencies 45...65Hz
  • Ability to perform measurements in short circuit system: phase-phase, phase-protective, phase-neutral
  • Differentiation between the phase voltage and the inter-phase voltage while calculating the shortcircuit current
  • Ability to change the length of test leads (measurement 23/42A)
  • Four-pole method, test leads do not require calibration (measurement 150/280A).
  • Touch voltage and touch shock voltage measurement with resistor 1kΩ) AC voltage measurement in range 0...440V.
  • Memory of 999 measurement results with an ability to transfer the data to a PC
  • Meter meets the requirements of the standard EN 61557
