If the meter is not used for a longer pe-
GB
riod, it is recommended to remove the bat-
tery to prevent any damage to the meter due
to battery leakage.

5.1 Connecting the test leads

The meter is supplied with two test leads (red
and black). They will allow to perform all meas-
urements except for temperature measure-
ments (
chapter 6.8):
1. The jack "COM" (12) is the common (-) jack
for all measurements. Connect the black
test lead to this jack.
2. The jack "V Hz Ω CAP °C °F" (11) is the
common (+) jack for all measurements, ex-
cept for measuring currents. Connect the
red test lead to this jack.
3. For measuring currents up to 400 mA, con-
nect the red test lead to the jack "µA / mA"
(5).
4. For measuring currents between 400 mA
and 10 A, connect the red test lead to the
jack "10A" (4).
For measuring, remove the protective caps
from the test tips and replace them after use.
IMPORTANT! To ensure protection of the
meter according to IP 67 (e. g. to protect it
against humidity for outdoor applications), in-
sert the sleeves (13) provided into the two red
jacks not used.

6 Measuring

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.
Caution: Before switching to another measur-
ing function, always remove the test tips from
the object to be measured to prevent damage
to the meter!

6.1 Measuring voltages

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 use this meter for measuring circuits
with corona discharges (high voltage).
Risk of electrocution!
G
The maximum voltage to be measured
must not exceed 1000 V¿/~, otherwise you
will risk your life!
Caution: Connect the red test lead to the jack
"V Hz Ω CAP °C °F" (11). If it is connected to
the jack "10A" (4) or "µA/mA" (5), the meter
and the object to be measured may be dam-
aged!
1) Set the selector switch (10) to the position
"V " to activate the mode "DC voltage
measurement" ("DC" will be displayed).
2) For AC voltage measurements, press the
button "MODE" (3) ["AC" will be displayed].
To return to "DC", press the button "MODE"
again.
3) Apply the test tips to the object to be meas-
ured and read the value on the display. If the
red test tip is applied to the negative pole
and the black tip to the positive pole when
measuring DC voltages, there will be a
minus sign in front of the value displayed.

6.2 Measuring currents

G
The current to be measured must not ex-
ceed 10 A!
1) For measurements up to 400 mA, connect
the red test lead to the jack "µA/mA" (5); for
measurements up to 10 A, connect it to the
jack "10A" (4). With unknown currents, start
with the 10 A range to be on the safe side.
2) According to the intensity of current, set the
selector switch (10) to the following position:
up to 4000 µA
> 4000 µA to 400 mA
> 400 mA to 10 A
The mode "DC current measurement" will
be activated ("DC" will be displayed).
3) For AC current measurements, press the
button "MODE" (3) ["AC" will be displayed].
position "µA "
position "mA "
position "10A "
