dC voltage measuring (dCV)
Turn the function knob to DCV position
•
and select the right range. If the voltage
is unknown, turn the function knob to the
highest range and repeat the measuring.
Connect the test leads to the measuring

points.
dC Current measuring (dCa)
Turn the function knob to DCA position
•
and select the right range. If the voltage is
unknown, turn the function knob to highest
range and repeat the measuring.
Connect the test leads to the measuring
•
points.
aC Voltage measuring (aCV)
Turn the function knob to ACV position
•
and select the right range. If the voltage
is unknown, turn the function knob to the
highest range and start the measuring.
Connect the test leads to the measuring

points.
Battery check
Turn the knob to 9V or 1,5V position
•
Connect the test leads to the battery.
•
transistor measuring (hFe)
Turn the function knob to hFE position.
•
Check if the transistor is a NPN or PNP type
•
and place the emitter, base and the collector
to the right socket in the front panel.
diode and continuity test with beep sound
Turn the function knob to position.
•
Connect the test leads to a diode, circuit or
•
resistance.
M
aintenance
Your multimeter is a precision electronic device.
Do not touch the circuit board.
to avoid any hazard please keep this advice
below:
Do not connect more than 250V DC/AC RMS-t.
•
Never connect voltage source to the meter in
•
Ω position!
Operate the meter only if the battery cover on.
•
Only change the battery after the device
•
switched the and the test leads has been
removed.
Change the battery if the appears
•
display or the measured value is unpunctual.
