Continuity Test; Fi/Rcd Trip Test; Backlighting; Frequency Measurement - METREL MD 1155 Manual De Instrucciones

Operation

Continuity test

Place the test probes on the line to test, fuse or similar. For a resistance of
0 - 2 kΩ, the resistance values appears on the display and an acoustic signal
sounds up to approx. 50Ω. If the measurement value is >2 kΩ, the over-
range indication „OL" appears on the display.

FI/RCD trip test

The Metrel
a FI/RCD circuit breaker using two buttons (FI\RCD). The FI/RCD
(max. 30 mA) is checked between the phase and circuit breaker (max. 240 V).

Backlighting

The display backlighting is permanent

Frequency measurement
