05. Operation

Function test

Check that the appliance is functioning reliably on a
known voltage source before each voltage check. The
LED lights up as soon as a voltage over 50 V is present,
even if the battery power is very low.
If you press the 'auto test' button, all LEDs for the voltage
measurement 5 and the LED indicator for the continuity
check 8 light up. An audible tone also signals acousti-
cally that the 'auto test' was successful.
The voltage checker must be taken out of operation if
it does not exhibit any function or if individual indicator
lamps do not work. A defective voltage checker must
not be used.
