Operation
Note
Do not use the ELV LED for measure-
ment purposes!
Note
Voltages have priority. If there is no
voltage at the test probes (< 4 V), the
device is in continuity check mode. In
stand-by mode the orange LED "Rx/Ω"
is lit.
To switch the device on, hold both test probes
■
together.
3 All optical displays of the device light up.
3 The device switches to continuity check.
Self-test
Touch the test probes together for this test.
■
3 The "Rx/Ω" LED must clearly light up green.
If the LED does not light up or only lights up
■
weakly, insert new batteries.
If the device does not function even with new
■
batteries, it must be checked by a specialist
technician.
After a short time the device switches off automati-
cally due to the "Auto Power Off" function.
3 The orange "Rx/Ω" LED goes out.
DC voltage check
Hold the test probes in contact with a DC
■
voltage that is within the nominal voltage range.
3 One of the lower LEDs (12 V +~-) and the LEDs
above it light up, corresponding to the voltage
that is present.
3 The lower LEDs indicate the polarity according
to the markings on the test probes! (+, -)
3 When the limit value of approximately 110 V/
DC is exceeded, the ELV LED comes on. This sig-
nals the presence of a potentially fatal voltage!
AC voltage check
Hold the test probes in contact with an AC
■
voltage that is within the nominal voltage range.
3 Both of the lower LEDs (12 V +~-) and the LEDs
above it light up, corresponding to the voltage
that is present.
3 The simultaneous lighting up of the lower LEDs
indicates an AC voltage (~).
3 When the limit value of approximately 45 V/AC
is exceeded, the ELV LED comes on. This signals
the presence of a potentially fatal voltage!

Line conductor test
Touch a conductor with test probe "L2".
■
3 On contact with a phase voltage of at least
100 V~, the "<L" LED lights up!
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.
You can also determine the phases by checking the
phase conductor relative to the protective conduc-
tor. If the phase conductors is checked the voltage
present should be indicated.
Note
Recall that in this test an additional
current flows along the protective
conductor. This is added to an already
existing current and could trigger the
circuit breaker (RCD)!
Phase sequence (rotary field) check
(max. 400 V)
Fully grip handles L1 and L2.
■
Hold test probes L1 and L2 against two outer
■
conductors (phases).
Check whether the phase voltage of e.g. 400 V
■
is present.
3 A clockwise rotating field (phase L1 before
phase L2) is indicated when the "R" LED lights
up.
3 An anti-clockwise rotating field (phase L2 before
phase L1) is indicated when the "L" LED lights
up.
The rotary field check must always be repeated with
reversed test probes. This must cause the direction of
rotation to change.
Note
The rotary field check can be
performed above 200 V, 50/60 Hz
(phase relative to phase) in the earthed
3-phase AC grid.
Single-handed check
The two handpieces can be locked (spacer on the
measuring lead).
The distance between the measuring tips can be
adjusted simply by turning. (Schuko socket/CEE)
