Current Measurement
• Set the rotary switch to current measuring rang, and select the preferred range.
• According voltage measurement requirements, select the DC or AC function.
• Inert the black test lead into COM jack, red test lead into mA jack or A input jack.
• Remove the power from the circuit under test and discharge the capacitors of the circuit.
• Break the circuit under test, connect the black test lead to the more negative side of the break,
and connect the red test lead to the more positive side of break.
• Read the value in the LCD display.
Note:
• The meter has two inputs "A", one labeled "10A" and other labeled "mA". The first is designed
to evaluate currents up to 10 amps, while the second is intended to evaluate milliamps (up to
approximately 600 mA). If you are unsure which one to use, choose the larger setting ("10A")
to avoid overloading the device.
• By preparing the multimeter to handle higher than expected amperage, you also prevent
fuses from blowing out in the event of an unpredictably strong current. If the current is much
higher than the amperage setting, you may damage the device.
Diode test and Continuity Check
• Set the rotary switch to
• Insert the black test lead into COM jack, red test lead into V/Ω jack.
• Place the red test lead on the anode of diode and black test lead on the cathode of diode, the
meter will show the approx. forward voltage of diode, reverse voltage will indicate 1 or OL.
• Touch the probes on the circuit or wire you want to check. The maximum value of the
resistance under verification will be shown on the display. If the resistance is less than 30Ω,
the beeper will sound.
• Read the values in LCD display. Diode unit is "V"; continuity unit is "Ω"
Note:
• Disconnect power to the unit under test and discharge all capacitors before taking diode test.
• To avoid damage the meter, do not input any voltage.
• Press the "FUNC" button to select the Diode / Continuity test.
