Electronic Component Testing Cheatsheet

[sausage]

I've finally finished my cheatsheet for testing electronic components. This was originally made for myself as fast reminder how to test certain components all in one place, but I've schooshed it up for public use. The intended audience is for beginners and intermediate repairers, menders, etc, not really for EEs or experts:

I hope this can serve as a handy reference.

Gas Discharge Tubes are meant to have a very high impedance below their breakdown voltage, not zero ohms. They are typically connected across a supply or a cable run exposed to lightning, etc.

Gas Glass Surge Arrestors / Gas Glass Discharge Tubes

Switch to continuity mode.

Connect the probe at both ends.

If you get a continuity beep then the tube is good. Otherwise it is bad.

Thanks fzabkar, will fix this.

Bourns gas-discharge tube surge arrestors are rated for 75 to 600 V breakdown (depending on part number), so they will be impossible to test with a normal DVM.

I've removed this component for now.
