AC/DC Voltage Measurements
CAUTION:
Do not measure voltages if a motor on the circuit is being switched ON or OFF. Large
voltage surges may occur that can damage the meter.
1. Rotate the function switch to the
VAC or the VDC
position.
2.
Insert the black test lead banana plug into the negative
COM
jack.
Insert the red test lead banana plug into the positive
V
jack.
3.
Touch the black test probe tip to the negative side of the circuit.
Touch the red test probe tip to the positive side of the circuit.
4.
Read the voltage value in the display.
Resistance, Diode, Continuity Measurements
Note: Remove power from the device under test before making resistance measurements
1. Set the function switch to the
position.
2.
Insert the black test lead banana plug into the negative
COM
jack.
Insert the red test lead banana plug into the positive
jack.
3.
Touch the black test probe tip to one side of the device.
Touch the red test probe tip to the other side of the device.
4.
Read the resistance value in the display.
5. Press
the
MODE
button to select the
DIODE
mode. The Diode symbol will
appear in the display.
6. Press
the
MODE
button to select the
Continuity
mode. The continuity symbol
will appear in the display. If the resistance is <150 ohms the tone will sound.
