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 ...

Have you ever found the need to measure the capacitance of a capacitor? No multimeter handy (for shame)? Well, as it turns out you can actually measure capacitance using your Arduino Uno, with no ...

If you need to measure capacitance but don’t have the necessary meter, you may be able to build a circuit that can handle the task. For example, if you have a data-acquisition board or module that ...

If you are just starting out in electronics, you need tools. But it is hard to build all your tools. Even though we see a lot of soldering station builds, you really ought to have a soldering iron to ...

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 ...

BEAVERTON, OR. Tektronix Inc. has announced the availability of two new source-measure unit (SMU) modules for the Keithley 4200A-SCS parameter analyzer that can perform low-current measurements even ...

Megger’s new CDAX 605 test set measure capacitance and dissipation factor at high voltages. Faster and easier to use than self-balancing capacitance bridges, the CDAX 605 combines an exceptionally ...

An optimal way to determine an op amp's input capacitance. Steps involved in making the input-capacitance measurement. 1. With a series resistor at the op-amp input, the input capacitance of the op ...

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 ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...
