5 Measuring

GB
Caution: Before switching over to another measuring function, always
remove the test tips from the object to be measured to prevent damage
to the meter!

5.1 Measuring voltages

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 250 V¿/~,
otherwise you will risk your life!
Caution: When measuring voltages, do not connect the red test lead to
the jack "10A" (7), otherwise the meter and the object to be measured
may be damaged!
1) Set the selector switch (6) to the position "V ".
2) Once the switch has been set to this position, the DC voltage meas-
urement will be activated ("DC" will be displayed). For AC voltage
measurements, press the button "MODE" (3) ["AC" will be displayed].
To return to DC voltage measurement, press the button "MODE" again.
3) Apply the test tips to the object to be measured 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.

5.2 Measuring currents

G
The current to be measured must not exceed 10 A!
G
Currents between 400 mA and 10 A must not be measured for more
than 30 seconds. There must be an interval of 15 minutes between
18
WARNING: Measurements in circuits carrying more than
42 V must only be made by persons able to recognize a
hazard of contact and to take the required safety precautions.
In case of measurements with a hazard of contact, avoid
working on your own. Ask a second person to assist.
WARNING: Take into account unexpected voltages on ob-
jects to be measured. Capacitors, for example, may be dan-
gerously charged even if the voltage source has been
switched off.
