Preparation for tests

6. Preparation for tests

• 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.

• 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.

• 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

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).

• 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.
