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.
