3. Choose an appropriate measurement range according to its scope.
Table 2-7 Capacitance Measurement Characteristics
Ranges* 2nF, 20nF, 200nF, 2μF, 200μF, 10000μF
Input Protection 1000V on all ranges (HI terminal)
Configurable
Parameters
Range, REL
NOTE*: All the ranges enable to obtain 20% ranges higher than original. Besides, both
Manual and Auto are available for setting every range.
4. Set relative value (Optional)
Press REL to open or close Relative math function. When it is open, “REL” is
shown over the screen and the reading displayed is a relative value which
comes from the result of actual measurement value subtracts the value that
has been set. (For the details about how to set, please refer to “
Math
Functions” in Chapter 2.)
7. Read the measurement result
Capacitance measurement is fixed at “Slow” rate, 3.5 digits resolution.
Therefore, you cannot adjust the reading rate when reading the result.
5. View history data
Press History to enter into the following interface and check the data getting
from this measurement and save.
Figure 2-25 View interface of History information
There are three types of way for viewing historical date: “Info”, “List” and
“HistoG”. Press Save after checking. By pressing Update, the History
information will be refreshed to be current newest information.
NOTE
Before measuring the electrolytic capacitance, you should make the two
legs of the electrolytic capacitance short circuit and let it be discharged.
