Continuity Test
Never test continuity
on a live circuit.
WARNING:
1. Set the rotary function switch to the position.
2. Press the
MODE
button until the symbol appears
on the display.
3. Insert the black test lead into the
COM
input jack and the red test lead into
the
Ω
input jack.
4. Touch the test lead probes to the device
or wire under test.
5. A beeper will sound if the resistance is
50 ohms or less and the resistance value
will be shown on the LCD display.
Operation cont.
1. Set the rotary function switch to the position.
2. Press the
MODE
button until the
“
Ω
” symbol appears on the display.
3. Insert the black test lead into the
COM
input jack and the red test
lead into the
Ω
input jack.
4. Touch the test lead probes to the
component under test. If the
component is installed in a circuit,
it is best to disconnect one side before testing
to eliminate interference from other devices.
5. Read the resistance on the LCD display.
Resistance Measurements
Never test resistance
on a live circuit.
