Measuring Capacitance
This measurement function is applicable for U1192A, U1193A, and U1194A
models only.
Set up your clamp meter to measure capacitance as shown in
the test points, and read the display.
To avoid possible damage to the clamp meter or to the equipment under
CAUTION
test, disconnect circuit power and discharge all high-voltage capacitors
before measuring capacitance. Use the DC voltage function to confirm that
the capacitor is fully discharged.
The clamp meter measures capacitance by charging the capacitor with a known
NOTE
current for a known period of time, measuring the resulting voltage, and then
calculating the capacitance.

For measuring capacitance values greater than 1000 μF, discharge the capacitor
NOTE
first, then select a suitable range for measurement. This will speed up the
measurement time and also ensure that the correct capacitance value is
obtained.
