Safety Measures

The testers have been constructed and tested in accordance with the safety regulations for voltage testers and have left the factory in a safe and perfect
condition.
The operating instructions contain information and references required for the safe operation and use of the tester. Before using the tester, read the operating instructions carefully and follow them in all respects.
Depending on the internal impedance of the voltage
tester there will be a different capability of indicating the presence or absence of operating voltage in case of the presence of interference voltage.
A voltage tester of relatively low internal impedance, compared to the reference value of 100 kΩ, will not indicate all interference voltages having an original voltage value above the ELV level. When in contact with the parts to be tested, the voltage tester may discharge temporarily the interference voltage to a level below the ELV, but it will be back to the original value when the voltage tester is removed.
When the indication “voltage present” does not appear, it is highly recommended to install earthing equipment before work.
A voltage tester of relatively high internal impedance, compared to the reference value of 100 kΩ, may not permit to clearly indicate the absence of operating voltage in case of the presence of interference voltage.
When the indication “voltage present” appears on a part that is expected to be disconnected of the installation, it is highly recommended to confirm by another means (e.g. use of an adequate voltage tester, visual check of the disconnecting point of the electric circuit, etc.) that there is no operating volt-age on the part to be tested and to conclude that the voltage indicated by the voltage detector is an interference voltage.
A voltage tester declaring two values of internal impedance has passed a performance test of man-aging interference voltages and is (within technical limits) able to distinguish operating voltage from interference voltage and has a means to directly or indirectly indicate which type of voltage is present.

The danger of electric shock and other dangers

To avoid an electric shock, observe the precautions when working with voltages exceeding 120 V (60 V) DC or 50 V (25 V) eff AC. In accordance with DIN VDE these values represent the threshold contact voltages (values in brackets refer to limited ranges, e.g. in agricultural areas).
The tester must not be used with the battery compartment open
Before using the tester, ensure that the test lead and device are in perfect working order. Look out e.g. for broken cables or leaking batteries.
Hold the tester and accessories by the designated grip areas only, the display elements must not be covered. Never touch the test probes.
The tester may be used only within the specified measurement ranges and in low-voltage installations up to 1000VAC and 1500VDC.
The tester may be used only in the measuring circuit category it has been designed for.
Before and after use, always check that the tester is in perfect working order (e.g. on a known voltage source).
Make sure that the cables tested for current are double insulated.
The tester must no longer be used if one or more functions fail or if no functionality is indicated.
It is not permitted to use the tester during rain or precipitation.
A perfect display is guaranteed only within a temperature range of -15°C to +55°C at relative air humidity less than 85%.
If the safety of the user cannot be guaranteed, the tester must be switched off and secured against unintentional use.
Safety is no longer guaranteed e.g. in the following cases:
— obvious damage
— broken housing, cracks in the housing
—if the tester can no longer perform the required measurements/ tests
— stored for too long in unfavorable 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 an explosive environment
The tester must be operated by trained users only
Operational safety is no longer guaranteed if the tester is modified or altered.
The tester may be opened by an authorized service technician only.
The current test may only be performed on double insulated cables.

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.

Preparation for tests

Auto-power-on/ switching on

The tester switches on when it detects short tips, or an AC or DC voltage above approx. 6 V or a live phase on L2+ (single pole test).
It can be switched on with a button.

Auto-power off

Tester is automatically powered off after approx.10 sec when there is no signal contacted to the probes.
The torchlight automatically switches off after approx. 30 sec.

Conducting Tests

Voltage test

Connect both probes to the object under test.
The voltage is indicated by LEDs if >120 V.
The buzzer and vibration function turn on if the voltage is higher than 50 V AC or 120 V DC.
Voltage polarity is indicated in the following manner on LCD.
▶AC: AC symbol is on
▶+DC: DC symbol is on
▶-DC: – symbol and DC symbol is on
Above 120 V, the polarity is shown on the LED display as well.
▶AC: both 120 V LEDs are on
▶+DC: left 120 V LED is on
▶-DC: right 120 V LED is on
Once when the tester is powered on, it will automatically measure voltage in the range 6V-1000VAC/1500VDC.
During voltage test, L or R LED/Symbol may light up.
In the case of empty batteries, only the ELV LED lights up >50 V.

Low Voltage mode –1V-1000VAC/1500VDC

Press the On/Off/Function button repeated until LCD shows <10V symbol.
In Low Voltage mode, it is possible to measure AC and DC voltage from 1V.

Continuity mode is disabled in Low Voltage Mode.

Current test

Press the On/off/ Function button repeated until LCD shows A symbol.
In the current test mode, currents between 0.1 A and 200 A can be tested.
The cable needs to be positioned in the center of the opening at the height of the markings left and right.
Make sure that only double insulated cables are measured.
Store test probes safely to avoid any unintended connection.
Tester switch to voltage measurement if the voltage is detected >6 V

Single-pole phase test

The function of this test may not be fully achieved if the insulation condition/ grounding conditions of the 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. Live circuit LED lights up and the buzzer sounds when a voltage of approx. 100 V AC or more exists in the object under test. (Pol_100 V AC).
Indication of Single Pole is via LED.

Phase rotation test

L LED (symbol) and R LED (symbol) for the Phase rotation test may operate on various wiring systems, but the effective testing results can be obtained only on a three-phase 4-wire system.
Hold the tester well in your hand and connect both probes to the object under test.
Phase-to-phase voltage is indicated by Voltage LEDs and LCD.
R LED lights up for the Right rotary field.
L LED lights up for the Left rotary field.
Measurement principle: The instrument detects the phase rising order regarding the user as earth.
The function of this test may not be fully achieved if the insulation condition/ grounding conditions of the user or of the equipment under the test are not good enough.

Continuity test L Rx

Make sure the object under test isn’t live.

Connect both test probes to the object under test.
Continuity is shown by the light-up of the LED and a sound if resistance is below 500 kOhm.
If a lower threshold for continuity is preferred, a low continuity mode can be selected.
Press Torchlight-function button repeated until LCD shows LRx symbol is shown on LCD.
Continuity is shown by light-up of LED and sound if resistance is below 20 Ohm.
▶Continuity test performed automatically in all modes except in Low Voltage and Current mode.
