Capacitance Measurement - UNI-T UT8803 User Manual

7.Capacitance measurement

a) Insert red test lead to C jack, black test lead to COM jack.
b) Switch the dial to ** position, connect test leads with capacitor in parallel.
c) Reading is displayed,
d) Press to manually switch the range.
e) Press to switch Q/R functions, long press this button to return to capacitance measurement.
Note:
If the circuit being measurement is shorted or the capacitance is over range, OL will appear.
There may be dozens of remaining digits because of the intrinsic capacitors. Please reset the reading
to 0 before measurement.
Method:
1. When the test leads in open status and frequency is 1kHz, press REL to reset the reading to zero.
2. When the test leads are shorted and frequency is 100Hz, press REL to reset the reading to zero.
For capacitor over 600μF, it takes long time to obtain reading.
Before measurement, please switch off all power supply and fully discharge all capacitors.
Pay particular attention to capacitors with high voltage.
Do not input voltage over 30V (sine wave RMS), (peak value 42V) or DC 60V.
Disconnect test leads with the circuit after measurement.
