( 3 customer reviews )

Description

Measurements of impedance in a short circuit loop.

  • L-PE circuit,
  • L-N, L-L circuit,
  • L-PE(RCD) circuit – without tripping the circuit breaker ≥ 30 mA.

Low voltage resistance measurement:

  • continuity measurement – DC current +200 mA with wire resistivity reset
  • low current resistance measurement with accoustic signalling,

the measurements are posible in instalations 220/380 V, 230/400 V, 240/415 V with frequeency range 45…65 Hz.

memory of 10 banks of 99 cells each (min.10000 records).
