-  During the tests, touch the device at the insulated 

test probes 7 and 8 only and do not touch the 

testing electrodes 6! 

-  Check the device for correct functioning immedi-

ately before and after using it (see chapter 3)! Do 

not use the device, if one or more indications are 

not working or if it does not seem to be ready for 

operation! 

-  If it is assumed that safe operation is no longer 

possible, the device must be switched off immedi-

ately.

-  Absolutely prevent the device from getting wet 

and avoid any water condensation at the device. 

Moreover, the device must be protected against 

contamination and damaging!

-  The device does not work with the battery being 

exhausted!

-  The device must be used within the stated nomi-

nal voltage range and in electrical installations of 

up to 400 V AC/DC only! 

-  The device must be used only in electric circuits 

of overvoltage category CAT III with max. 300 V 

for phase-to-earth measurements. For measure-

ments within measuring category III, the protrud-

ing conductive part of a testing electrode 6 of 

the measuring line must not be longer than 4 mm. 

Before carrying out measurements within measur-

ing category III, the enclosed attachable protective 

caps marked with CAT III must be pushed onto 

the testing electrodes 6 for user protection pur-

poses.

-   Please observe that work on live parts and elec-

trical components of all kinds is dangerous! Even 

low voltages of 30 V AC and 60 V DC may be 

dangerous to human life!

-   Do not operate the device with the battery com-

partment being open.

-   The device is designed for being used by qualified 

electricians and under safe working conditions. 

-   Do not dismantle the device! 

Immediately before use, make absolutely sure that the 

system part to be tested is free of voltage! For this pur-

pose, use a two-pole voltage tester.

The device is provided with a high-power LED torch. 

Do not look directly or indirectly via reflecting surfaces 

into the LED beam. An LED beam might cause irrepa-

rable damage to your eyes.

-   Check the device for correct functioning immedi-

ately before and after using it!

-  Press and hold the push-button  for approx. 5 

seconds to check all LEDs, the LED torch and the 

buzzer for correct functioning. 

-  Short-circuit the test probes 7 and 8 to test the 

internal measuring circuit, the measuring lines 

and the batteries. The buzzer must sound and the 

LEDs  1,  2 and 3 for continuity test must light 

up. 

-  Please replace the batteries as soon as the LEDs 

1

,  2 and 3 are flashing during the continuity 

test.

-   Test the LEDs 4 and 5 of the external-voltage 

indication as well as the correct functioning of the 

single-pole external conductor test (phase) 4 with 

familiar voltage sources, e.g. with a 230 V socket.

-  Do not use the device, if not all functions are 

working properly!

-  The continuity and diode test must be carried out 

on system parts which are free of voltage. If nec-
