    4. EXPLANATION 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 Battery replacement symbol...
  • Page 10: Carrying Out Measurements

    7. 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.
  • Page 11: Rotating Field Direction Display

    The applied voltage is shown on the LCD display. The Low-Imp LED signals low impedance measurement. The maximum permitted duty cycle in low impedance operating mode is 5 seconds for voltages up to 250V and 3 seconds for voltages up to 690V.
  • Page 12: Continuity Check

    10. CONTINUITY CHECK The voltage tester can also be used as a continuity tester. Always hold the voltage tester by the handles designed for this purpose. Never touch the device beyond the handle ends. The continuity tester switches itself on automatically when the test starts, and switches itself back off when the test has been completed.
  • Page 13: Maintenance And Disposal

    12. MAINTENANCE AND DISPOSAL Check the technical safety of the voltage tester 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 •...
