Intended Use; Testers Information; Device Elements; Display Elements - Greenlee GT50-NE Mode D'emploi

Safety is no longer guaranteed e.g. in the following cases:
- obvious damage
- broken housing, cracks in housing
- if the tester can no longer perform the required measurements/
tests
- stored for too long in unfavourable conditions
- damaged during transport
- leaking batteries
The tester complies with all EMC regulations. Nevertheless it can
happen in rare cases that electric devices are disturbed by the
electrical field of the tester or the tester is disturbed by electrical
devices.
Never use the tester in explosive environment
Tester must be operated by trained users only
Operational safety is no longer guaranteed if the tester is modi-
fied or altered.
The tester may be opened by an authorized service technician
only.
5.1

Intended Use

The tester may be used only under the conditions and for the
purposes for which it was designed. Therefore, observe in particular
the safety instructions, the technical data including environmental
conditions.

Testers Information

6.1

Device elements

1. Test probe, L1 (-)
2. Torchlight button
3. LED indication
4. Test tip, L2 (+)
6.2

Display elements

1. Single pole test; ELV warning
2. Voltage indication
3. LEDs indicating 6 V and polarity
4. Rotary field - L(left) and R(right)

Preparation for tests

7.1 Auto-power-on/ switching on
• The tester switches on when it detects shorten tips, or an AC
or DC voltage above approx. 10 V or a live phase on + (single
pole test)
• It can be switched on with the
7.2 Auto-power off
• Tester is automatically powered off after approx.10 sec when
there is no signal contacted to the probes
• The torch light automatically switches off after approx. 30 sec.
7.3

Voltage test

• Connect both probes to the object under test
• The voltage is indicated by LED
- Buzzer sounds when a threshold voltage is >50 V AC/DC or
>120 VDC
• Voltage polarity is indicated in following manner:
- AC: + and -6 V LED are both on
- +DC: +6 V LED is on
- - DC: -6 V LED is on
