F. Measuring Capacitance
Figure 3-6. Capacitance Measurement
Warning
To ensure accuracy, the Meter inside is discharged
against the tested capacitor. "DIS.C" will be shown
on the display when it is under discharging, this
process will be quite slow.
To avoid damage to the Meter or to the equipment
under test, disconnect circuit power and discharge
all high-voltage capacitors before measuring
capacitance.
Use the DC Voltage function to confirm that the capacitor
is discharged.
To measure capacitance, set up the Meter as shown
in Figure 3-6 and proceed as follows:
Insert the red test lead into the terminal and
the black test lead into the
COM terminal.
