gain optimal and accurate measurement results.
8-1 Selecting Test Frequency
Test frequency can greatly affect the results of measurement reading,especially
when measuring inductors and capacitors. This section provides some
recommendations and suggestions to consider.
Capacitance
When measuring capacitance selecting, the right frequency is important in
obtaining the most accurate measurement results. Generally,a 1 kHz test
frequency is used to measure capacitors that are 0.01 µF or smaller. For
capacitors that are 10 µF or larger, a lower frequency of 120 Hz is used. Following
this trend,high test frequencies are best for testing very low capacitance
components. For large capacitance components, low frequency would be optimal.
For example, if the capacitance of the component is to be in the mF range, than
selecting 100 Hz or 120 Hz for test frequency would give much better results. The
results will also be obvious because if the same component was tested with 1 kHz
or 10 kHz, the measured readings may look erroneous on the display. In all cases,
it is best to check with the manufacturer’s data sheet in order to determine the
best test frequency to use for measurement.
