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] ...

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 ...

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, ...

Our last article covered voltage troubleshooting in series with power-consuming devices (motors) [“Electrical Troubleshooting,” March 5, p. 16]. The article differentiated between an open and a closed ...

Equally at home in the laboratory, the workshop or in the field, on the bench or on the ground, Megger’s new heavy duty DLRO10HD low resistance ohmmeter combines rugged construction with accuracy and ...

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 ...

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 ...
