WARNING
The accuracy of the functions might be slightly affected, when exposed to
a radiated electromagnetic field environment, eg, radio, telephone or
similar.
Continuity Measurements
1. Set the Function/Range switch to the " " position.
2. Remove power from the equipment under test.
3. Connect the red test lead to the " + " jack and the black test lead to the "COM"
jack.
4. Touch the probes to the test points. the beeper sounds continuously, if the
resistance is less than 50
W
±30
W
.
Diode Tests
1. Connect the red test lead to the " + " jack and the black test lead to the "COM"
jack.
2. Set the Function/Range switch to the " " position.
3. Turn off power to the circuit under test.
4. Touch probes to the diode. A forward-voltage drop is about 0.6V (typical for
a silicon diode).
5. Reverse probes. If the diode is good, "OL" is displayed. If the diode is
shorted, ".000" or another number is displayed.
6. If the diode is open, "OL" is displayed in both directions.
