Resistance Measurement
• Set the rotary switch to resistance range.
• Insert the black test lead into COM jack, red test lead into V/ jack.
• Touch the test probe tips across the circuit or part under test.
• Read the value in LCD display.
Note:
• Disconnect power to the unit under test and discharge all capacitors before test.
• To avoid damage the meter, do not input any voltage.
Capacitance Measurement
• Set the rotary switch to capacitance range.
• Insert the black test lead into COM jack, red test lead into mA CX jack.
• Discharge all capacitors under testing.
• Touch the test leads to the capacitor to be tested, black test lead connect the negative and
red test lead connect the positive of capacitor.
• Read the value in LCD display.
• When measuring the small value capacitors, meter may not return zero due to interfere,
subtract the residual value in LCD displayed during the measurement.
Note:
• Disconnect power to the unit under test and discharge all capacitors before test.
• To avoid damage the meter, do not input any voltage.
Frequency Measurement
• Set the rotary switch to frequency range.
• Insert the black test lead into COM jack, red test lead into V/ jack.
• Touch the test lead tips to the circuit under test.
• Read the frequency value in the LCD display.
Note:
• Press the "FUNC" button to select the "Hz" or "%" test function.
• To avoid electric shock, do not apply more than 250 Vdc before making Frequency
measurement.
