  • Page 9: Measurement Operations - Measuring Ac Current

    MEASUREMENT OPERATIONS - MEASURING AC CURRENT • Set the measuring function range of AC current by rotating the dial to A . The meter will be within the measuring function range of AC current as default. • Clamp the instrument to the input current signal to be tested.
  • Page 10: Measuring Ac Voltage

    MEASURING AC VOLTAGE • Insert the black probe into the “COM” input and the red probe into the “V Ω” input. • Set the measuring function range of AC voltage by rotating the dial to V • The Meter will be within the measuring function range of AC voltage as default.
  • Page 11: Measuring Resistance

    MEASURING RESISTANCE • Insert the black probe into the “COM” input and the red probe into the “V Ω” input, ready for measurement. • Set the measuring function range to Resistance by rotating the dial to the “Ω” symbol. • Place the two probes across the circuit elements to be tested.
  • Page 12: Diode Measurement

    DIODE MEASUREMENT • Insert the black probe into the “COM” input and the red probe into the “V Ω” input, ready for measurement. • Set the measuring function range by rotating the dial so it aims at the “ ” symbol. •...
  • Page 13: Measuring Induced Voltage (Ncv)

    MEASURING INDUCED VOLTAGE (NCV) • Set the measuring function range by rotating the dial so it aims at “NCV”. • The top right end of the clamp head is equipped with an electromagnetic induction sensor, which is able to detect whether the alternating current magnetic field exists or not.
