Voltage measurement
To make a voltage measurement, first connect the test leads to the meter. Then select
“V“ with
the rotary switch. You can select alternating current or direct current with the
“
FUNC/ZERO
“ key.
Now touch the object to be tested with the test tips. The display will now show the reading.
Note:
Due to the meter
’s sensitivity, measured values may occur even when the test leads are
not connected. When the reading exceeds 600 V DC, AC (RMS), a sound can be heard.

Resistance measurement, continuity and diode test
To make a resistance measurement, a continuity test or diode test, first connect the test leads to
the meter. Then select
“
Ω“ with the rotary switch. With the “
FUNC/ZERO
“ key, you can now
select one of the functions. Now touch the object to be tested with the test tips. The measured
value will be shown in the display.
7.3.1
Resistance measurement
When
“OL“ is displayed, this means that the circuit is open or the measurement has been
exceeded. When measuring high resistances, e. g. >1 M
Ω, it can take a few seconds until a stable
reading is displayed.
7.3.2
Diode test
The voltage drop in the forward direction of the diode is measured approximately. If the test leads
are connected with reversed polarity, "OL" is displayed.
7.3.3
Continuity test
As soon as the reading is <50
Ω, a sound can be heard. When the reading is >400 Ω, ”OL“ will
be displayed.
7.3.4
Capacitance measurement
When making a capacitance measurement, the measured capacitors are charged. To ensure an
accurate result, the capacitors must be discharged completely before making a measurement.
The meter as well as the test leads can increase the readings.

Replacing the batteries
When the battery icon appears in the display, the batteries must be replaced to make sure the
meter works properly. This will be the case when the battery voltage is <2.4 V.
To replace the batteries, first disconnect the test leads from the meter. Now turn off the meter.
You can now open the battery compartment at the rear side of the meter to replace the batteries.
Insert two new 1.5 V AAA batteries. Observe correct polarity. Close the battery compartment. The
meter should now work fine again.
