2 Measurements
2.1 Tester operation control
Before each operation of the tester, its func-
tioning must be checked:
•
Test the voltage indicator using a known volt-
age source,
•
Short-circuit the measurement probes – there
should be a sound signal, the LED diode
Ω
should be lit and there should be the
legend in the display.
Notes:
The voltage indication function is active
whether the batteries are charged or not. Other
functions require charged batteries.
