Making Measurements
19
The meter measures capacitance by charging the
capacitor with a known current for a known period of time,
measuring the resulting voltage, then calculating the
capacitance. The measurement takes about 1 second per
range. The capacitor charge can be up to 1.2 V.
The meter’s capacitance ranges are 5 nF, 0.05 µF,
0.5 µF, and 5 µF.
To measure capacitance, set up the meter as shown in
Figure 5.
The following are some tips for measuring capacitance:
• To speed up measurements of similar values, press
Kto manually select the proper range.
• To improve the accuracy of measurements less than
5 nF, use the relative (REL) mode to subtract the
residual capacitance of the meter and leads.
