3. Choose a proper capacitance range according to the measured circuit.
Table 2- 7 Measurement Characteristics of Capacitance
Ranges*
2nF、20nF、200nF、2μF、200μF、200μF、10000μF
Input Protection 1000V on all ranges (HI terminal)
Configurable Parameters Range, Rel
NOTE*:
All the ranges enable to obtain 20% value higher than original. Besides, both
Manual and Auto are available for setting every range.
4. Set relative value (Optional operation).
Press 【Rel】to open or close Relative math function. When it is opened, the
reading displayed is a relative value which comes from the result of actual
measurement value subtracts the value that has been set. (Please refer to
“ Math Functions” in Chapter 2 to know about the details.)
5. Read measurement result.
Capacitance measurement is fixed at “Slow” rate. Therefore, you can’t
adjust the reading rate when reading the result.
6. View history data.
There are four types of way to view historical data: “Number”, “Bar
Meter” ”Trend Chart” and “Histogram”.
NOTE：
Before measuring the electrolytic capacitance, you should make the two legs
of the electrolytic capacitance short circuit and let it be discharged.
