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 jack.
4) Press the MODE button until “Ω” displays on the screen.
5) Touch the test probe tips across the circuit or part being tested. It is
best to disconnect one side of the part being tested so the rest of the
circuit will not interfere with the resistance reading.
6) Read the resistance displayed on the screen.
CONTINUITY CHECK
To avoid electric shock, never measure continuity on circuits or wires that
have voltage on them.
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 VΩCAP jack.
4) Press the MODE button until displays on the screen.
5) Touch the test probe tips across the circuit or wire you want to check.
6) If the resistance is less than approximately 35Ω, the audible signal will
sound.
DIODE TEST
The value that displays on screen during the diode check is the forward
voltage.
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 VΩCAP jack.
4) Press the MODE button until display on the screen.
5) Touch the test probes to the diode or semiconductor being tested.
6) Reverse the probe polarity by switching probe position. Note this
reading.
7) The diode or junction can be evaluated as follows:
