RESISTANCE MEASUREMENT
WARNING: To avoid electric shock, disconnect power to the unit under test and
discharge all capacitors before taking any resistance measurements. Remove the
batteries and unplug the line cords.
1. Set the function switch to the Ω position.
2. Touch the test probe tips across the circuit or part under test. It is best to disconnect
one side of the part under test so the rest of the circuit will not interfere with the
resistance reading.
3. Read the resistance in the display
CONTINUITY CHECK
WARNING: To avoid electric shock, never measure continuity on circuits or wires that
have voltage on them.
1. Set the function switch to the
2. Press the
button to indicate
3. Touch the test probe tips to the circuit or wire you wish to check.
4. If the resistance is less than approximately 150Ω, the audible signal will sound. If the
circuit is open, the display will indicate "OL".
DIODE TEST
1. Set the function switch to the
2. Press the
button to indicate
3. Touch the test probes to the diode under test. Forward voltage will typically indicate
0.400 to 0.700V. Reverse voltage will indicate "OL". Shorted devices will indicate near
0V and on open device will indicate "OL" in both polarities.
Non-Contact AC Voltage Measurements
WARNING: Risk of Electrocution. Before use, always test the Voltage Detector on a
known live circuit to verify proper operation
1. Touch the probe tip to the hot conductor or insert into the hot side of the electrical outlet.
2. If AC voltage is present, the detector light will illuminate.
NOTE: The conductors in electrical cord sets are often twisted. For best results, rub
the probe tip along a length of the cord to assure placing the tip in close proximity to
the live conductor.
NOTE: The detector is designed with high sensitivity. Static electricity or other
sources of energy may randomly trip the sensor. This is normal operation
