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.
7.0 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.
☞
I n case of low 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 well in your hand. Connect the “L2
+” probe to the object under test.
Single pole 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 ope-
rate 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 probes to the object under the test.
•
Phase-to-phase voltage is indicated by Voltage LEDs.
•
R LED lights up for Right rotary field.
•
L LED lights up for Left rotary field.
•
Measurement principle: The instrument detects the
phase rising order regarding the user as earth.
☞
Function of this test may not be fully achieved if the
insulation condition/ grounding conditions of user
or of the equipment under test is not good enough.
