4.2 Attaching the ATTENTION! label

GB
Labels with important infor-
mation in eight languages are
supplied with the meter. At-
tach the corresponding label
in your language to the field
provided on the cover of the
battery compartment!

4.3 Connecting the test leads

The meter is equipped with four test jacks:
1. The jack COM (12) is the common (-) jack
for all measurements. Connect the black
test lead to this jack.
2. The jack V Ω
mon (+) jack for all measurements, except
for current measurements. Connect the red
test lead to this jack.
3. For current measurements up to 400 mA,
disconnect the red test lead and connect it
to the jack µA/mA (5).
4. For current measurements between 400 mA
and 10 A, disconnect the red test lead and
connect it to the jack 10A (4).
IMPORTANT! For outdoor operation of the
multimeter, insert the protective sleeves sup-
plied (13) into the two test jacks that are not
used. Only this will ensure protection of the unit
in accordance with IP 67.

5 Measurements

WARNING Measurements in circuits carry-
ing more than 42 V must only be
made by persons able to recog-
nize a hazard of contact and to
take the required safety precau-
tions. In case of measurements
with a hazard of contact, avoid
working on your own. Ask a sec-
ond person to assist.
Prior to switching over to another test function,
remove the probe tips from the object to be
measured, otherwise the multimeter may be
damaged!

ATTENTION!
To prevent the danger of
an electric shock, the probe
tips must be removed from
the connecting jacks and
the measuring spots prior
to opening the housing.
Fuses are inserted to pro-
tect against overvoltage
and fire hazard. Faulty fuses
must only be replaced by
fuses of the same type!

5.1 Voltage measurement

WARNING Take into account unexpected
voltages on objects to be meas-
ured. Capacitors, for example,
may be dangerously charged
even if the voltage source has
been switched off.
G
Never perform measurements in electric
circuits with corona discharges (high volt-
age) with this meter. Risk of electrocution!
G
The maximum voltage to be measured
must not exceed 1000 V¿/~, otherwise you
will risk your life!
1) Set the selector switch (10) to the position V.
After switching on, the DC voltage measure-
ment will always be activated: The display
(6) will indicate "DC" at the top on the left.
For AC voltage measurements, switch over
to the indication "AC" with the button MODE
(3). The button MODE also allows to return
to the DC voltage measurement.
2) The red test lead must be connected to the
jack V Ω CAP Hz% (11).
Caution! The test lead must not be con-
nected to the jack 10A (4) or µA/mA (5),
otherwise the meter and the object to be
measured may be damaged.
3) Apply the probe tips to the object to be meas-
ured and read the value on the display. If, for
DC voltage measurements, the red probe
tip is applied to the negative pole and the
black tip to the positive pole, a minus sign
will precede the measured value.
4) During an AC voltage measurement, the
button Hz% (2) allows to switch over to fre-
quency measurement and duty cycle meas-
urement, however, the input sensitivity will
not be as high and the frequency range will
not be as large as that for a measurement in
the position Hz% of the selector switch:
Measuring range Sensitivity
4 V~ ≥ 1.5 V~
≥ 10 V~
40 V~, 400 V~
≥ 20 V~
1000 V~ ≥ 420 V~
To return to AC voltage measurement, press
the button Hz% once or twice so that the dis-
play will indicate "AC" and "V" again.
Frequency range
5 Hz – 10 kHz
5 Hz – 20 kHz
5 Hz – 200 kHz
50 Hz – 1 kHz
