Preparation for Tests
Control elements
1. Buzzer hole for acoustic indication
2. Singel Pole Test ELV Warning
3. Continuity Test
4. Rotary field (left and right)
5. LCD Display indicating voltage, polarity and low battery
6. LEDs indicating 12V and polarity
7. Voltage Indication
6. Preparation for Tests
6.1 Auto-power-on/ switching on
•
The tester switches on when it detects continuity, an AC
or DC voltage above apporx. 10V a live phase on L2
(single pole test).
•
It can be switched on with the torch light button.
6.2 Auto-power off
•
Tester is automatically powered off after 5 sec when
there is no signal contacted to the probes.
•
The torch light switches off after approx. 10 sec.
7. Conducting Tests
Safety advices
•
Depending on the internal impedance of the voltage de-
tector there will be a different capability of indicating the
presence or absence of operating voltage in case of the
presence of interference voltage.
•
A voltage detector of relatively low internal impedance,
compared to the reference value of 100 k
Ω
, will not in-
dicate all interference voltages having an original voltage
value above the ELV level. When in contact with the parts
to be tested, the voltage detector may discharge tempo-
rarily the interference voltage to a level below the ELV,
but it will be back to the original value when the voltage
detector is removed.
•
When the indication
“voltage
present”
does not appear,
it is highly recommended installing earthing equipment
before work.
