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.
resistance measuring (Ω)
•
Turn the function knob to OHM 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 on the
display or the measured value is unpunctual.
