One of my go-to diagnostic tools is a simple home-brew audible ohmmeter (AudOhm). This circuit has served me well for many years, allowing “heads up” testing of wiring harnesses and control equipment, ...

What can you do if you want to measure the heating effects of a power device? Since the parametric analyzer cannot provide continuous high power to cause self-heating, a different approach is needed.

Description: This multifunction megohmmeter is capable of producing 125V, 250V, 500V, and 1,000V test voltages for insulation resistance measurements up to 4000MΩ. It also tests AC/DC voltages up to 1 ...
