Possible measurements

• Short-circuit loop measurement:
  - impedance measurement with 23A current (44A phase-to-phase) - short-circuit resistor R=10Ω,
  - measurement range: 95...440V, frequency 45...65Hz,
• Short-circuit loop measurement with resolution 0,01Ω, in distribution network without tiggering RCD (IΔn≥30mA):
  - 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 1000mA. (Type AC, A and B).
• Measurement of insulation resistance:
  - with test voltage 250V, 500V, 1000V,
  - measurement range up to 3GΩ,
  - UNI-Schuko plug for insulation measurement,
  - automatic discharging after measurement,
  - automatic measurement of all resistences in 3,4,5-wire cables using optional adapter AUTO-ISO,
  - acoustic signals in 5sec intervals for insulation resistance characteristic, 
  - safety measurement - protection against overvoltage.
• Measurement of earthing resistance.
• Bi-directional testing of PE wire continuity using 200mA current.
  - Autocalibration of test leads.
