RESISTANCE MEASUREMENTS
1. Set the Function/Range switch to the "
Ω
" position. Use the " / /
" button to select the resistance test.
2. Turn off power to the circuit under test. External Voltage across the
components causes invalid reading.
3. Connect the red test lead to the "V
Ω
" jack and the black test lead to the
"COM" jack.
4. Connect the test leads to the points of measurements and read the
value from the display.
CONTINUITY MEASUREMENTS
1. Set the Funtion switch to the " " position. Use the " / / " button
to select the continuity test.
2. Turn off power to the circuit under test. External Voltage across the
components causes invalid reading.
3. Connect the test leads to the two points at which continuity is to be
tested. The buzzer will sound if the resistance is less than approxi-
mately 30
Ω
.
DIODE TESTS
1. Set the Function/Range switch to the " " position. Use the " / /
" button to select the diode test.
2. Turn off power to the circuit under test. External voltage across the
components causes invalid readings.
3. Connect the red test lead to the "V
Ω
" jack and the black test lead to
the "COM" jack.
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 diaplayed. If the diode is
shorted, "0.00" or another number is displayed.
6. If the diode is open, "OL" is displayed in both directions.
7.Audible Indication: Less than 0.03V.
