  • Page 9: Back Light Button

    4.1. Back Light Button The back light button is used to turn the back light on only. To extend the battery life, the back light will be turned off automatically within around 3 seconds. 4.2. DC Voltage Measurements Caution: Do not measure DC voltages if a motor on the circuit is being switched ON or OFF.

  • Page 10: Dc Current Measurement

    4.4. DC Current Measurements Caution: Do not make current measurements on the 20A scale for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads. Insert the black test lead banana plug into the negative (COM) jack.

  • Page 11: Resistance Measurement

    Apply power to the circuit. Read the current on the display. The display will indicate the proper decimal point value. 4.6. Resistance Measurements Warning: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements.

  • Page 12: Frequency Measurement

    Reverse the probe polarity by switching probe positions. Note the reading. The diode or junction can be evaluated as follows: A. If one reading shows a value and the other reading shows “1", the diode is good. B. If both readings show “1", the device is open. C.

  • Page 13: Replacing The Battery

    Insert the temperature probe into the negative jack (COM) and the positive jack (Temperature), making sure to observe the correct polarity. Touch the temperature probe head to the part whose temperature you wish to measure. Keep the probe touching the part under test until the reading stabilises (about 30 seconds) Read the temperature on the display.

  • Page 14: Replacing The Fuse

    Note: If your meter does not work properly, check the fuses and battery to make sure that they are still good and that they are properly inserted. 7. Replacing the Fuses Warning: To avoid electric shock, disconnect the test leads from any source of voltage before removing the back cover.
