7.8. Capacitance measurements
Caution!
Turn off power and discharge the capacitor before attempting a capacitance measurement. Use the
DCV function to confirm that the capacitor is discharged.
1. Press -| |- - button.
2. Insert red test lead to V/Ω/Hz-input and black test lead to the COM-input.
3. Connect the test leads to the capacitor. Observe polarity when measuring polarized capacitors.
4. Read the capacitance directly from the display. A shorted capacitor will indicate an over range.
An open capacitor will indicate near zero on all ranges.
7.9. Measuring Frequency
Warning !!
Do not try to measure the frequency of a signal that exceeds 250 volts AC
rms
. It may damage your
instrument and expose yourself to a severe shock hazard.
Follow these steps to measure the frequency of a signal.
1. Press Function-Switch "Hz".
2. Plug the black test lead into the COM-terminal and the red test lead into the V/Ω-terminal.
3. Connect the test lead to the frequency source. It will automatically select and display appropriate
frequency ranges up to 200 kHz.
Warning:
When the test leads are connected to an AC outlet, do not select other ranges. It might damage the
internal components or cause bodily injury.
Notes:
* For the most accurate frequency measurements, we strongly recommend you to use a BNC cable
with ferrite core.
