DC testing of solid dielectric cable is largely ineffective, highly discouraged, and discontinued by most. The preferred method is to use AC voltage to test cables, and for long cable runs, a Very Low ...

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 ...

Used with a DMM on the 20V range, this circuit gives a rapid and direct measure of the leakage current of capacitors. There are two ranges, with maximum readings of about 20µA and 2mA, and the test ...
