CAUTION
To avoid electric shock, instrument damage and/or equipment damage.
Do not exceed 10Vdc while set to take measurements in the battery test
range.
3. Connect the test leads to the 1.5Vdc battery under test.
Normally a good 1.5Vdc battery will read above 1.25Vdc.
Consult the battery manufacturer for complete battery specifica-
tions to determine actual battery life remaining and condition of
battery

DIODE TESTS
1. Connect the red test lead to the "VΩ" 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. External voltage across
the components causes invalid readings.
4. Touch probes to the diodes. A forward-voltage drop is about
0.6V (typical for a silicon diode).
5. Reverse probes. If the diode is good, "1" is displayed. If the
diode is shorted, ".000" or another number is displayed.
6. If the diode is open, "1" is displayed in both directions.
7. If the junction is measured in a circuit and a low reading is
obtained with both lead connections, the junction may be shunt-
ed by a resistance of less than 1kΩ. In this case the diode must
be disconnected from the circuit for accurate testing.
Sec. 9.6
NON CONTACT VOLTAGE (NCV) TESTS
1. Switch to "OFF", push "NCV" button.
2. Check device with a known live current source (wall receptacle
or cord). The Volt Sensor is operative if the red LED light
remains on and the "beep" sound continues in close proximity of
a cord connected to a power source.
3. After checking the above performance, you may now test the
circuitry in question.
