8.1. Preparing the test
Prior to every test, please ensure that the instrument is in perfect condition:
• For example, keep an eye out for broken housing or leaking batteries.
• Always carry out a function test before using the voltage tester, see
below.
• Check that the instrument is functioning perfectly (for example at a
known voltage source) before and after every test.
• If the safety of the user cannot be guaranteed, the instrument must be
switched off and secured to prevent unintentional usage.
Carrying out a function test
> Press HOLD for approx. 2 s.
- Instrument carries out a self-test. All segments of the LC display and
the alarm, along with the measuring point and display illumination, are
activated for approx. 2 s.
Recording a reading
> A reading is displayed: press the HOLD key.
- A short acoustic signal is emitted and the LC display shows the
recorded reading.
> To delete the recorded value, press the HOLD button once again.
- A short acoustic signal is emitted.
The recorded value will automatically be deleted after approx. 10 seconds
once voltage is no longer being applied to the probe tips. This is indicated
by a short acoustic signal.
Voltages below 6 V AC/DC cannot be recorded, ---- is shown on the LC
display.
Removing/installing the probe tip protector/extension
The probe tip protector and extension can be removed/installed as required.
Attention: Use of the probe tip protector may be required depending on the
national regulations or provisions!
> Probe tip protector: push onto probe tips or pull off.
> Probe tip extension: screw onto probe tips or unscrew.
8.2. Voltage testing
> Connect both probe tips to the test object.
- The instrument switches on automatically at a voltage of approximately
6 V or above.
- The voltage is shown in the LC display.
- In the case of DC voltage, the polarity of the indicated voltage relates
to the voltage tester probe tip.
