Considerations
Test Frequency. The test frequency is user selectable and can be
changed. Generally, a 1 KHz test signal or higher is used to measure
capacitors that are 0.01uF or smaller and a 120Hz test signal is used
for capacitors that are 10uF or larger. Typically a 1 kHz test signal or
higher is used to measure inductors that are used in audio and RF
(radio frequency) circuits. This is because these components operate
at higher frequencies and require that they be measured at a higher
frequency of 1 KHz. Generally, inductors below 2mH should be
measured at 1 kHz and inductors above 200H should be measured at
120Hz.
It is best to check with the component manufacturers’ data sheet to
determine the best test frequency for the device.
