Capacitance Measurements
WARNING:
To avoid electric shock, disconnect power to the unit under test
and discharge all capacitors before taking any capacitance measurements.
Remove the batteries and unplug the line cords.
1. Set the function switch to the
Ω
position.
2. Insert the black test lead banana plug into the
negative
COM
jack. Insert the red test lead banana
plug into the positive
V
jack.
3. Press the
MODE
button to indicate “
nF
” on the
display.
4. Touch the test leads to the capacitor to be tested.
5. The test may take up to 3 minutes or more for large
capacitors to charge. Wait until the readings settle
before ending the test.
6. Read the capacitance value in the display.
1. Set the function switch to the “
Hz %
” position.
2. Press the Hz/% button to indicate “
Hz
” in the display.
3. Insert the black lead banana plug into the negative
COM
jack and the red test lead banana plug into the
positive
Hz
jack.
4. Touch the test probe tips to the circuit under test.
5. Read the frequency on the display.
6. Press the
Hz/%
button again to indicate “
%
” on the
display.
7. Read the % of duty cycle on the display.
