An old Electronics Designer’s Casebook described a circuit that provided capacitance measurements of 10 pF to 1 µF with 1% accuracy (Reference 1). A number of issues emerged with the circuit during ...

Normally, a typical multimeter is designed to measure parameters such as voltage, current and resistance over a wide range of values. This analog capacitance meter has 5 switched range values of 1nF, ...

ABB has announced the development of a portable capacitance meter, the CB-2000, that is simpler to use and easier to carry than any other measuring devices previously available. ABB has announced the ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

[Mike] sent in a project he’s been working on lately. This little circuit can measure the capacitance of a capacitor by generating a frequency that’s inversely related to the capacitance. He ...

You don’t see them much anymore, but there was a time when any hobbyist who dealt with RF probably had a grid dip meter. The ...
