General

Voltages have priority. If no voltage is applied at the measurement probes (< 3.0 V), the
appliance is in the continuous/ resistance test mode.

Function

To switch on the device, simply hold the test probes on one another.
Attaching and removing the measuring probe adapter makes it easier to carry out mea-
surements at the socket.
Indication of the voltage is carried out without the batteries.

Self-test

For the test, keep the probes apart. The test buzzer must clearly sound and the indicati-
on must display approx. „000". If the LC display does not, or only faintly illuminates, re-
place the batteries. If the appliance does not function with the new batteries, it must be
protected from misuse.

Checking the DC voltage

When placing the probes on a DC voltage within the rated voltage range, the voltage is
indicated in Volts and „DC" also appears on the display. If a negative voltage is applied at
the probe „L2", a „−" (minus) is indicated in front of the value. From a voltage of approx.
35 V, the hazardous voltage is indicated by a flashing LED behind the display and an a-
coustic, vibrating signal is indicated. If the batteries are completely discharged, if voltage
is applied, a warning triangle is indicated on the display.

Check AC voltage (TRMS)

When placing the probes on an AC voltage within the rated voltage range, the voltage is
indicated in Volts and „AC" also appears on the display. The mains frequency is also in-
dicated. From a voltage of approx. 35 V, the hazardous voltage is indicated by a flashing
LED behind the display and an acoustic signal is indicated.
If the batteries are completely discharged, if voltage is applied, a warning triangle is indi-
cated on the display.

DATA HOLD function

By briefly activating the „L.H." button (save data), a measurement value can be saved on
the LC display. The „DATA HOLD" function is indicated on the display by the symbol
„D.H." and can be switched off by again briefly activating the button.

Phase test

Contact a conductor with the probe L2. If a phase is applied, min. 100 V~, appears on the
LC display „<L".
For determining the phase conductor, the perceptibility of the indication can be impaired,
e.g. by insulating fixtures to protect against direct contact, in adverse positions, for exa-
mple on wooden ladders or insulating floor coverings, of a voltage not earthed or also in
adverse lighting conditions.
