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 approx. 6V or
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 30 sec when there is no signal contacted to the
probes.
•
The torch light switches off after approx. 30 sec.
6.3
Self-Test
•
When voltage tester is off short both probes L1 and L2, hold probes shorted.
•
All LEDs, all symbols on LCD and buzzer will be on for a 2s.
•
Self-test will start automatically when replacing batteries.
If some of LEDs is not ON, or some LCD symbols are not ON or Buzzer or Torch light is
not ON, the device is not safe for use. Replace the battery and start Self-Test again. If
some of these indications are not ON again, the device is not safe for use and must NOT
be used.
Do not use tester while Self-Test procedure is activated.
7. Conducting Tests
7.1
Voltage test
•
Connect both probes to the object under test.
•
The voltage is indicated by LEDs and LCD
•
Buzzer sounds when a threshold voltage of 50VAC or approx. 120 VDC is exceeded.
•
Voltage polarity is indicated in following manner.
➢
AC: + and
– 12V LED are on
➢
+DC: +12V LED is on
➢
-DC: -12V
LED is on (and “-“ is shown on LCD)
When the L2 probe + is the positive (negative) potential, the Polarity indication LED
indicates “+DC” (“-DC”).
During voltage test, L or R LED may light up.
In case of empty batteries, the ELV LED lights up >50VAC, >120VDC
