Sonel MZC-304 Loop Impedance Meter - CATIV

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.
