Page 8: Explanations Of Symbols
Explanations of Symbols The voltage tester shows the following symbols: DC voltage AC voltage DC voltage negative potential (DC) Phase display from 100 to 690V ~ 50/60Hz when used as a „single-pole“ phase tester. Continuity test symbol Rotating field display clockwise Rotating field display anticlockwise Device for work to be performed with voltage present... - Page 9 lid (9) with a suitable screwdriver and remove it. • Insert two micro-batteries (AAA) into the battery compartment. Observe the polarity information in the battery compartment. If possible, use alkaline batteries.They guarantee a longer service life. • Then, carefully close and screw down the battery compartment lid again.
- Page 10 same reason, we recommend that you remove flat batteries immediately. Function test / Self test: Test the voltage tester on a known source. Warning: To avoid electric shock, disconnect the test leads from any source of voltage before turn on the self-check test function. The “!”...
- Page 11 Carrying out Measurements The twin-pole voltage tester has two handles, a connecting cable and an LCD display. Always hold the voltage tester in such a way that you get a vertical view of the display. Strong incidence of light may have an adverse effect on the display. For DC measurements, test tip is the positive pole, and the test tip is the negative pole.
- Page 12 Voltage measurement with high internal impedance Always hold the voltage tester by the handles designed for this purpose. Never touch the device beyond the handle ends. Hold the two test tips onto the measuring points to be tested. The voltage tester switches on automatically with voltages higher than 4.5V AC/DC.

input impedances without time restrictions. The voltage tester also indicates a rotating direction (L or R) with measurements on single-phase mains (L1 against N). This is not a device malfunction. Rotating field direction display The voltage tester can show the direction of the rotating field with three-phase systems. - Page 14 switches itself on automatically when the test starts, and switches itself back off when the test has been completed. Check for correct functioning before beginning the test. If you connect the two test tips with each other, you should heap a beep, and the continuity LED should light up.

Check for correct functioning at a known alternating voltage source. Contact test tip “ ”L2”... - Page 16 regularly. It can be assumed that risk-free operation is no longer possible if: • there is visible evidence that the device has been damaged • the device has been stored under unfavorable conditions for a longer period of time • the device has been subjected to heavy transport strain.
- Page 17 batteries You, as the end user, are required by law (Battery Ordinance) to return all used batteries/rechargeable batteries. Disposing of them in the household waste is prohibited! Batteries/rechargeable batteries containing hazardous substances are marked by the shown symbols. These symbols also indicate that it is prohibited to dispose of them in the household waste.
