Battery type: 2 x micro 1.5 V AAA Alkaline
(do not use rechargeable batteries)
Enclosure: IP 50
Approval: to EN 61243-3
= VDE 0682 Part 401
Weight: 135 g
Battery installation:
Open the battery compart-
ment using a screwdriver or
a coin. With the rear side of
the unit facing up, turn the
catch clockwise through 45°
to unlock. Now pull the bat-
tery compartment out as far
as the stop. Install batteries
as indicated (do not use
rechargeable batteries). To
close the battery compart-
ment, push the battery com-
partment as far as it will go
into the housing and lock the
compartment in place by
turning the catch anticlock-
wise through 45°.
WARNING: Voltage tester
must not be used with the
battery compartment open.
Function test/battery test
With the test probes shorted
and pushbutton pressed the
entire LED step display must
come on briefly, leaving only
the +6 V step indicator on.
An acoustic signal will also
sound. If the +6 V step indi-
cator flashes during this test,
change the batteries at the
next opportunity possible.
The LED step display will
flash while conducting further
voltage/continuity checks to
remind you that the batteries
need changing.

Safety Instructions
ç
y
The voltage tester must
only be used within the
specified rated voltage
range. The provisions con-
tained in DIN VDE 0105
Part 100 and EN 50110-1
regarding the use of volt-
age testers stipulate that
just before testing for iso-
lation from supply, the
voltage tester must be
checked for proper work-
ing order. If the indicator
fails to operate during this
check, the voltage tester
must not be used.
y
Indication that the upper
limit for extra-low voltages
(ELV) has been exceeded
only serves as a warning
to the user and not as a
measurement reading.
y
Due to the high input
resistance, the capacitive
and inductive voltages
may be indicated.
yWhen testing, hold the
voltage tester by its hand-
les only. Do not touch the
test electrodes. Only per-
form 2-pole voltage tests.
y
Before using the voltage
tester in places where
noise levels are high,
first check whether the
accoustic test signal is
audible.
y
The LEDs start to glow at
80-85 % of designated
voltage.
y
Reliable indication is only
assured over a tempera-
ture range of –10 °C to
+55 °C.
y
The voltage tester must be
checked for proper work-
ing order shortly before
and after testing for isola-
tion from supply. If this
check reveals any failure
of the tester to indicate
one or more steps or if the
voltage tester fails to show
that it is ready for opera-
tion, it must not be used.
y
The voltage tester and its
accessories must not be
dismantled by unauthor-
ized persons.
y
The tester must be stored
in a dry and clean place.
y
The tester must not be
used in wet conditions
(e.g. condensation or rain)
(IP 50).
y
Within its maximum ON
duration, the device may
be exposed for up to 30
seconds to the maximum
rated voltage of the indi-
cated range.
y
Indicator legibility may be
impaired in adverse light
conditions, e.g. in sunlight.
y
WARNING: Voltage tester
must not be used with the
battery compartment open.
