  • Page 8: Dc Current Measurement

    DC CURRENT MEASUREMENT Do not measure 20A currents for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or test leads. 1) Insert the black test lead banana plug into the negative COM jack. • For current measurements up to 4000μA DC, set the function switch to the μA position and insert the red test lead banana plug into the μA jack.

    DC CURRENT MEASUREMENT Do not measure 20A currents for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or test leads. 1) Insert the black test lead banana plug into the negative COM jack. • For current measurements up to 4000μA DC, set the function switch to the μA position and insert the red test lead banana plug into the μA jack.
  • Page 10: Resistance Measurement

    RESISTANCE MEASUREMENT To avoid electric shock, disconnect power to the test area and discharge all capacitors before taking any resistance measurements. Remove the batteries and unplug the line cords. 1) Set the function switch to the Ω CAP position. 2) Insert the black test lead banana plug into the negative COM jack. 3) Insert the red test lead banana plug into the positive Ω...
  • Page 11: Capacitance Measurements

    A) If one reading shows a value and the other reading shows OL, the diode is good. B) If both readings show OL, the device is open. C) If both readings are very small or zero, the device is shorted. CAPACITANCE MEASUREMENTS To avoid electric shock, disconnect power to the area being tested and discharge all capacitors before taking any capacitance measurements.
