ACV/Hz Measurement

The voltage measurement range is of AC 0.0001V∼1000V and the measurement method is as follows:

  1. Turn on the power and press the SHIFT button and after V button.
  2. Insert the red and black testing lines into VΩHz end and COM end respectively.
  3. Connect the meter to the two ends of the measured voltage with the red and black probes.
  4. Read the meter’s data from the main display area, and read the signal’s frequency on the secondary display area. When OL displaying on the meter, it indicates the measured voltage exceeding the meter’s range and it is necessary to remove both the red and black probes from the measured circuit immediately. The Voltage frequency can be measured fewer than 60kHz.
  5. By pressing the RANGE key it is possible to select range manually. While displaying OL during manual range measurement, it is necessary to select a larger range. When OL displaying under the maximum range, it indicates the voltage exceeding 1000V, so it is necessary to remove both the red and black probes from the measured circuit immediately.
Notes: in case of probe hanging in the air, the voltage inducted by the testing line may cause unstable readings on the display screen, but that will not affect the accuracy of measurement.

Warning: Not try to measure a voltage higher than 1000V

    The measurement range of diode is of 0~2.2V.

    The measurement range of resistance is of 0~60MΩ.

    The measurement range of continuity is of 0~600Ω.

    The measurement methods are as follows:

    1. Turn on the power switch and press Ωto switching Resistance/Continuity/Diode.
    2. Insert the red testing line into the VΩHz end and the black testing line into the COM end.
    3. For the resistance measurement, connect the red and black probes to the two ends of resistor and read the resistance value from the main display area. While displaying OL during manual range measurement, it is necessary to select a larger range. When OL displaying under the maximum range, it indicates the resistor is larger than 60MΩ. As for the continuity measurement, connect the red and black probes to the two measured points respectively. In case of the resistance between the two points being less than about 50Ω~60Ω, the buzzer will sound while the display screen displaying the value of resistance. If OL displaying, it indicates the resistance between the two points is larger than 600Ω. As for the Diode measurement connect the red probe to the positive polarity of the diode and the black probe to its negative polarity, while the display screen will display the forward voltage drop. Connect the black probe to the positive polarity of the diode and the red probe to its negative polarity, if OL displaying on the display screen, it indicates the backward resistance of the diode being normal, while OL not displaying, it indicates that the drop of diode.

    Notes: In case of performing diode/resistance/continuity test on circuit board, it is necessary firstly to turn off the power of the circuit board and then perform the measurement. As there may be other parallel circuits, so the displayed value of test is not surely the results listed in items 3.

    How to measure capacitance using ABM-4081 multimeter?

    The measurement range of capacitance is of 0.1pF~60mF and the measurement methods are as follows:

    1. Turn on the power switch and press SHIFT + Hz% button.
    2. Insert the red and black testing lines into the VΩHz input end and the COM input end respectively.
    3. If exists voltage in the capacitor, connect the two ends of the capacitor for a short time to discharge.
    4. Connect the red and black probes to the two ends of the capacitor, if the measured capacitor is heteropolar, it is necessary to connect the red probe to the positive polarity of the capacitor and the black probe to its negative polarity.
    5. Read the capacitance from the display screen. While displaying OL during manual range measurement, it is necessary to select a larger range. When OL displaying under the maximum range, it indicates the capacitance value > 63mF, then meter will display OL, while capacitance value < 0.1pF, it will display zero.
    6. It is possible to select range manually by pressing the RANGE key.

    Notes: When performing measurement on 600μF...63000μF capacitor, in order to ensure measurement accuracy the meter takes a relative long time to discharge capacitor, so it is relatively slow in refreshing the measured value. In addition, not to perform Capacitance measurement on a circuit board on which there are other parallel devices, for that may leads to very large error.
