The fun of having a giant resistor-shaped Ohmmeter is that it reads back the resistance by displaying the color code. If you’re not too hot with decoding those bands there’s a helper band to the right ...

If you’ve got a resistor and you can’t read the color bands (or they’re not present), you can always just grab a multimeter and figure out its value that way. [Giacomo Yong Cuomo] and [Sophia Lin] ...

A simple ohmmeter is all that is needed to troubleshoot a potential relay. After taking all of the connecting wires off of the potential relay, measure the resistance across the 1 and 2 terminals. The ...

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, ...

The meters that can be used in this application are the DMS-20PC-0, DMS- 20LCD-0, DMS-30PC-0 and the DMS-30LCD-0. The “0” suffix on all these part numbers indicates that these meters have an input ...
