4.7 Resistance

1. Turn off all power and discharge capacitors on the
circuit under test.
2. Insert the red test lead in the "INPUT" jack and the
black lead in the "COM" jack.
3. Move the rotary switch to the "
the test leads across the circuit to be measured.
4. Read measured resistance on the LCD display. Tips for
measuring resistance:
- Sometimes the resistor value and measured resistance
differ. This is due to the meter's output test current goes
through all possible paths between leads.
- For low resistance measurements, short the test leads
and record the resistance displayed. Then connect to
the circuit and subtract the recorded resistance from
the measurement for the most accurate results.
- When leads are disconnected or measurement is out of
range, "OL" is displayed.
To avoid injury or damage to the meter, make sure to
turn off all power and discharge all capacitors before
measuring resistance.

4.8 Continuity

1. Turn off all power and discharge capacitors on the
circuit under test.
2. Insert the red test lead in the "INPUT" jack and the
black lead in the "COM" jack.
3. Move the rotary switch to the "
the test leads across the circuit to be measured. Read
measured resistance on the display. If the measured
resistance is less than 40Ω, the meter's buzzer will
sound.
