measuring tips the spot or circuit where you
wish to measure AC voltage.
If you do not know the voltage range before-
hand, set the largest possible range and gradually
decrease it as you measure.
3. Turn on the device you want to measure. The
screen will display the voltage value and polarity
relative to the red measuring tip.
If you exceed the range of 300 V, immediately
stop measuring. Otherwise, you risk damaging the
multimeter and suffering injury by electric current.
Measuring Direct Current
1. Connect the plug of the red measuring conduc-
tor into the
socket and the black conductor
into the COM socket. If the measured voltage
is between 200 mA and 10 A, connect the
plug of the red measuring conductor into the
10 A socket.
2. Turn the circular switch to function marked
.
3. Connect the multimeter serially to the circuit
you wish to measure and turn on the power
supply to the measured device.
4. The screen will display the measured current
and polarity relative to the red measuring tip.
Never use the device to measure current in
places where the idle voltage in an open circuit
exceeds 300 V.
Measuring current at higher idle voltage could result
in damage to the device (fuse burnout, electric
discharge) or injury by electric current!
Measuring Resistance
1. Connect the plug of the red measuring conduc-
tor into the
“ socket and the black conductor
into the COM socket.
2. Turn the circular switch to function marked .
Select measuring range. Turn off the power sup-
ply to the circuit and discharge all high-voltage
capacitors before measuring resistance in the
circuit. Doing so prevents potential damaging
of the multimeter.
3. Connect the measuring tips to the device or
circuit where you wish to measure resistance.
4. The screen will show the measured resistance
value.
Note:
1. When measuring resistances higher than 1 MΩ,
it is necessary to wait a few seconds before the
measured value stabilizes.
2. If the circuit is open, the ”OL” symbol will
appear, same as when the measuring range is
exceeded. Before measuring resistance, make
sure that the measured object is disconnected
from power supply and all its capacitors are
fully discharged.
Diode Test
1. Connect the plug of the red measuring conduc-
tor into the
socket and the black conductor
into the COM socket.
2. Turn the circular switch to function marked
.
3. Place the red measuring tip onto the diode‘s
anode and then the black measuring tip onto
the diode‘s cathode.
4. The screen will show voltage in mV for the
direction of current flow. „OL“ will appear on
the screen if the polarity has been reversed.
Circuit Continuity Test
1. Connect the plug of the red measuring conduc-
tor into the
socket and the black conductor
into the COM socket.
2. Turn the circular switch to function marked .
3. Connect the measuring tips to the tested circuit
or device. If resistance is lower than 20 Ω, you
will hear a buzzer.
Note: Before making measurements, make sure that
the measured circuit is disconnected from power
supply and all its capacitors are fully discharged.
Changing Batteries
If the display shows the
symbol, the battery
needs replacing. Use a suitable screwdriver to
change the battery.
Before changing the battery, disconnect the meas-
uring tips from the measured circuit or device and
turn the switch to the OFF position.
Unscrew the rear cover.
Replace the 9 V type 6F22 battery with a new one.
Use alkaline batteries only. Do not use rechargeable
batteries.
Make sure to observe the correct polarity. After
changing the battery, replace the cover and screw
it back on.
Replacing the Fuse
If the fuse burns out, it is most likely caused by
improper handling. The multimeter uses fuses with
these parameters:
F 250 mA/300 V, ø 5×20 mm, F 10 A/300 V,
ø 5×20 mm.
The fuse is located under the battery cover. Always
replace the fuse with a fuse of the same type and
parameters. Replace the battery cover and close
it shut.
To replace the F 10 A L 300 V fuse, contact a
service centre.
Before changing a fuse, disconnect the measuring
tips from the measured circuit or device and turn
the switch to the OFF position.
