5 Operation
NOTE
To protect the internal components, if a capacitor that is being tested has a
charge, the meter will first discharge the cap and show
diSC . After a complete
discharge the meter will conduct a normal test. diSC may also be displayed if
the incorrect input is provided (e.g., measuring voltage while in capacitance
mode).
1. Set the function switch to the position.
2. Insert the black probe lead into the negative COM terminal and the red probe
lead into the positive
terminal.
3. Touch the tips of the probe across the part under test.
4. Read the capacitance value on the display.
NOTE
For very large capacitance values, it may take several seconds for the
measurement to settle and the final reading to stabilize.
5.11 Continuity test
WARNING
Do not do diode, resistance, or continuity tests before you remove the power
from the capacitors and the other devices (when you do a test during a meas-
urement). Injury to persons can occur.
1. Set the function switch to the position.
2. Insert the black probe lead into the negative COM terminal and the red probe
lead into the positive
Ω terminal.
3. Use the button to select continuity measurement. The indicator will
be displayed.
4. Touch the tips of the probe across the circuit or component under test.
5. If the resistance is less than 30 Ω , the meter will beep.
