Measuring functions

The measuring tool offers the following measuring functions:

  • Testing and measuring alternating voltage
  • Testing and measuring direct voltage
  • Overload indication
  • Testing RCDs
  • Continuity testing
  • Single-Pole Phase Testing
  • Rotating Field Testing

  • Always use the test probe guard (12) in measuring environments according to CAT III and CAT IV.
  • Keep your fingers behind the finger guards while holding the handles.
  1. Touch the contacts to be tested with the L1 (2) and/or L2 (4) test probes, as shown in the figure.
  2. The result is indicated in the LED display (6).
  3. During voltage tests, the type of voltage and the voltage level are automatically detected and displayed.
  4. The LED display (6) indicates the relevant rated voltage range.

  • Do not take any measurements if the open-circuit potential to earth is more than 1000 V.
  1. Perform the test or measurement via  see Measuring Process .
  2. The voltage level (h) will be displayed on the measuring tool and the AC indicator will light up.

  1. Perform the test or measurement via  see Measuring Process .
  2. The voltage level (h) will be displayed on the measuring tool and the + and (DC) indicators will light up.

  1. Perform the test or measurement via  see Measuring Process .
  2. If the measuring tool is overloaded, all voltage levels (h) and the ELV indicator (a) will flash.

  1. Perform the test via  see Measuring Process .
  2. Press both buttons (8) at the same time during the test.
  3. The RCD is triggered, the measuring tool vibrates and an audio signal sounds.

The continuity test can be performed on cables, switches, relays, light bulbs or fuses, for example.

  1. Before carrying out the continuity test, make sure that the circuit to be tested is de-energised.
  2. Perform the test via  see Measuring Process .
  3. If the continuity test is successful, the indicator (c) lights up and an audio signal sounds.

  1. Perform the test via  see Measuring Process .
  2. The AC indicator flashes and the ELV (a) indicator lights up.
The single-pole phase test can be carried out in an earthed mains supply from 230 V, 50/60 Hz (phase to earth). With a single-pole phase test, the LED display (6) works unreliably under certain conditions. Protective clothing and insulating conditions on site may impair the function. Note: The absence of voltage can only be determined by a two-pole phase test.

The rotational direction (of the magnetic field) can only be determined in a system with three-phase alternating current.

  1. Perform the test via  see Measuring Process .
  2. The voltage and rotating field direction (L or R) will be indicated. R indicates that the presumed phase L1 is actually phase L1 and the suspected phase L2 is actually phase L2 of a clockwise rotating field. L indicates that the presumed phase L1 is actually phase L2 and the suspected phase L2 is actually phase L1 of a clockwise rotating field. For another test with the test probes interchanged, the opposite symbol will light up.
