[Jonathan’s] capacitance meter is just what I needed and I even threw it out to an Arduino that was already hooked up using the Arduino Create web interface, so that was easy. I actually used ...

Capacitance meters are instruments that measure capacitance, the ability to store an electric charge. They are used to test, inspect and sort ceramic and other types of capacitors on production lines.

A capacitance meter is a type of tester that reads the capacitor’s charge and may also monitor other impedance measurements including resistance and inductance. Capacitance testers measure different ...
