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
7.1 Voltage test
• Connect both probes to the object under test.
• The voltage is indicated by LEDs and LCD (3031 only)
• Buzzer sounds when a threshold voltage of approx.
38VAC or approx. 100 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
When the L2 probe + is the positive (negative) po-
tential, 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
7.2 Single-pole phase test
Function of this test may not be fully achieved if the
insulation condition/ grounding conditions of user
or of the equipment under test aren’t good enough.
Verification of live-circuit shouldn’t be dependent on
this Single-pole phase test only, but on the voltage
test.
• Hold the tester good in your hand. Connect the “L2+”
probe to the object under test. Live circuit LED lights up
and buzzer sounds when a voltage of approx. 100V AC
or more exists in the object under test. (Pol≥100VAC).
7.3 Phase rotation test
• L LED and R LED for Phase rotation test may operate on
various wiring systems, but effective testing result can be
obtained only on three-phase 4-wire system.
• Hold the tester good in your hand and connect both pro-
bes to the object under test.
• Phase-to-phase voltage is indicated by Voltage LEDs.
• R LED lights up for Right rotary field.
