Resistance Measurements
~WARNING: Never test resistance on a live circuit.
1. Set the rotary function switch to the highest o position .
2. Insert the black test lead into the COM input jack and insert
the red test lead into the o input jack .
3. Touch the test lead probes across the cir c uit or component
under test. It is best to disconnect one side of the device
under test so the rest of the ci rcuit will not interfere with
the resistance reading.
4. Read the resistance on the LCD display . If desired , turn the
rotary function switch to a lower O position (200k0, then
20k0 , then 2k0, then 2000) to obtain a more precise reading .

Operation cont.
Continuity Test
~WARNING: Never test continuity on a live circuit.
A Continuity Test is used to verify if the path for an electrical circuit is continuous
or unbroken . Only a closed or complete ci rcuit has continuity . During a continuity
test, the multimeter sends a small current through the circuit to measure
res i stance . The beeper will sound if the ci r cuit is found to be continuous .
1. Set the rotary function switch to the ·•l) position .
2. Insert the black test lead into the COM input jack and insert the red test
lead into the · •l) input jack .
3. Touch the test lead probes to the component or wire you wish to check.
4. If the res i stance is approximately 300 or less , an audible signal will sound .
If the resistance is above 2200 , the display will i ndicate "OL ". The resistance
will be shown on the display if it is below 2200 .
