Operation
General
Voltages have priority. If there is no voltage at the
test probes (< 3 V), the device is in continuity/resist-
ance test mode.
Operation
To switch the device on, hold both measuring probes
together. After a short time the device switches off
automatically due to the "Auto Power Off" function.
The remaining running time is displayed.
The screwing on or off of the measuring probe
adapter makes measuring at wall outlets more
convenient.
Self-test
Touch the test probes together for this test. The test
buzzer must sound clearly and the display must
indicate approximately "000". If the LCD does
not light up or lights up only weakly, the batteries
must be replaced. If the device does not function
even with new batteries, it must be protected from
improper use.
DC voltage check
Upon placing of the probe tips on a DC voltage
within the rated voltage range, the voltage is
displayed in volts and "DC" is additionally output
on the display. If a negative voltage is present at
probe tip "L1", then a "-" is displayed in front of the
value. For voltages greater than approximately 35
V, the potentially fatal voltage is indicated by the
LED flashing behind the display and an audible and
vibrating signal.
The voltage value is displayed even in
the batteries are discharged.
AC voltage (VRMS) check
Upon placing of the probe tips on an AC voltage
within the rated voltage range, the voltage is
displayed in volts and "AC" is additionally output
on the display. The mains frequency is likewise
displayed. For voltages greater than approximately
35 V, the potentially fatal voltage is indicated by
the LED flashing behind the display and an audible
signal.

The voltage value is displayed even in
the batteries are discharged.
DATA HOLD function
Brief pressing of the "L.H." key (data hold) saves the
measured value currently displayed on the LCD. The
"DATA HOLD" function is indicated by the symbol
"D.H." on the display field and can be switched off
again through a further pressing of the same key.
Phase check
Touch a conductor with test probe "L1".
On contact with a phase of at least 100 V~, the
indication "<L" is output to the LCD.
For determination of the phase conductor, the per-
ceptibility of the display may be impaired, e.g. by
insulating devices for protection against accidental
direct contact, in unfavourable positions, for exam-
ple on wooden ladders or insulating floor coverings,
a non-earthed voltage or under unfavourable light
conditions.
Rotary field check (max. 400 V)
Grip all round handles L 1 and L2.
Hold test probes L 1 and L2 against two outer
conductors (phases) and check whether the outer
conductor voltage of e.g. 400 V is measured.
A clockwise rotating field (phase L1 before phase
L2) is indicated if the letter "R" is output to the
display.
An anti-clockwise rotating field (phase L2 before
phase L1) is indicated if the letter "L" is output to the
display.
The rotary field check must always be repeated with
reversed test probes. The direction of rotation must
thereby change.
The rotary field check can be
performed above 200 V, 50/60 Hz
(phase against phase) in the earthed
3-phase AC grid.
Single-handed check
Thanks to the spacer located on the measuring line,
locking of the two hand parts is possible.
The distance between the test probes can be
adjusted simply by turning. (Schuko/CEE plug)
