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 position.
2. Insert the black lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive jack.
3. Touch the test probe tips to the circuit or wire you wish to check.
4. If the resistance is less than approximately 150 , the audible signal will
sound. If the circuit is open, the display will indicate 1 .
DIODE TEST
1. Insert the black test lead banana plug into the negative COM jack and the
red test lead banana plug into the positive diode jack.
2. Turn the rotary switch to the position.
3. Touch the test probes to the diode under test. Forward bias will typically
indicate 400 to 1000. Reverse bias will indicate 1 . Shorted devices will
indicate near 0 and the continuity beeper will sound. An open device will
indicate 1 in both polarities.
TEMPERATURE MEASUREMENTS
1. Set the function switch to the TEMP position.
2. Insert the Temperature Probe into the Temperature Socket, making sure to
observe the correct polarity.
3. Press the ºC or ºF button for the desired units.
4. Touch the Temperature Probe head to the part whose temperature you
wish to measure. Keep the probe touching the part under test until the
reading stabilizes.
5. Read the temperature in the display.
Note: The temperature probe is fitted with a type K mini connector. A mini
connector to banana connector adaptor is supplied for connection to the
input banana jacks.
