Analogue reading: to get the resistance in
Ω
, multiply the reading
on the 50 scale by the reading coefficient shown in the table.
7 - RESISTANCES
Never test a resistance on a live circuit.
If the “Voltest” light comes on, presence of a voltage U > 10 V
AC/DC. Unplug the leads immediately and cut off the voltage
before making the resistance measurement.
■
Connect to the terminals of the circuit or the component to test.
Do not use the A AC input on unprotected current
transformers
