Resistance Measurements

WARNING:
Never test resistance
on a live circuit.
1. Set the rotary function switch to the
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 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.

Continuity Test

WARNING:
Never test continuity
on a live circuit.
