Continuity Test; Single-Pole Phase Test; Phase Rotation Test; Torch Light - Greenlee GT50-NE Mode D'emploi

Once the tester is powered on, it will automatically measure
voltage in the range of 6 V-690 V

When the L2 probe + is the positive (negative) potential, the
Polarity indication LED indicates '+DC' ('-DC')

In case of empty batteries: 50/120/230/400/690 V LEDs still
indicate the presence of voltage
7.4
Make sure the object under test isn't live.
• Connect both test probes to the object under test
-
-
-
This test is only possible when batteries are installed and in good
condition
7.5

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 a 2-pole voltage test.

Firmly grasp the insulated grips of the main body of the tester in
order to increase the sensitivity of single-pole phase test.

Hold the tester good in your hand. Connect the '+' probe to the
object under test.

Live circuit LED lights up and buzzer sounds when a voltage of
approx. 100 VAC or more is detected on the object under test.
(Pol≥100 VAC).

Single pole indication is via LED
The single-pole phase test is only possible when batteries are
installed and in good condition
7.6
• L LED (symbol) and R LED (symbol) for phase rotation test may
operate on various wiring systems, but effective testing result
can be obtained only on three-phase 4-wire system
• Firmly grasp the insulated grip of the tester probe L2, it is better
for the sensitivity of the phase rotation test and connect both
probes to the object under 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.
• Testing of phase-sequence direction is possible from 100 VAC
voltage (phase to phase) provided the neutral is earthed
• 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
7.7
• Press the
will turn itself off
7.8
• LEDs up to 50 V, torch light, ELV indication and buzzer are
turned on for a second after battery replacement or selftest
activation. Selftest can be activated:
Shorting L1(-) and L2(+) probe tips while device is turned
OFF – leave device OFF for 30 seconds before shortening tips

Continuity test

Continuity test is performed automatically
Buzzer/Continuity LED lights up and buzzer sounds
continuously to indicate continuity
Tester switch to voltage measurement if voltage is
detected during continuity testing >6 V

Single-pole phase test

Phase rotation test

Torch light

button to turn on the light and after approx. 30 s it
