10.4 RESISTANCE MEASUREMENT

Do not conduct resistance measurements on live circuits. Make sure
all capacitors in the circuit are depleted.
1. Connect the black test lead to the "COM" jack and the red test lead to
the input jack.
2. Set the selection button to the desired "
3. Press the SEL function button to select the "" measurement.
4. Connect the test leads across the source under measurement.
5. Read the voltage value on the LCD display.
Notes
• If the resistance being measured is connected to a circuit, turn off the
power and discharge all capacitors before applying the test probes.
• An over-range is indicated by OL.

10.5 DIODE MEASUREMENT

Do not conduct diode measurements on live circuits. Make sure all
capacitors in the circuit are depleted.
1. Connect the black test lead to the "COM" jack and the red test lead to
the input jack.
2. Set the selection switch to the desired "
3. Press the SEL function button to select "
4. Connect the test leads across the source under measurement.
5. Read the value on the LCD display.

10.6 CONTINUITY TEST

Do not conduct continuity measurements on live circuits. Make sure
all capacitors in the circuit are depleted.
1. Connect the black test lead to the "COM" jack and the red test lead to
the input jack.
2. Set the selection switch to the desired "
3. Press the selection button to choose the " " measurement.
4. Connect the test leads to two points of the circuit to be tested. If
continuity exists, the built-in buzzer will sound.
