2 - DESCRIPTION
3 “FUS” LIGHT
Neon for testing the 1.6 A and 16 A fuses on current measurement.
If the “Fus.” light comes on, change the faulty fuse(s).
NB: This light requires the presence of a voltage
≥
100 V to come on.
4 “VOLTEST” LIGHT
Voltage presence light on ohmmeter.
If the “Voltest” light comes on: presence of a voltage U > 15 V
AC/DC.Unplug the leads and cut off the voltage before making
the resistance measurement.
