Testing Varistor at Mackenzie Balfour blog

Testing Varistor. Touch one meter probe to the free varistor lead and the other probe to the connected lead. Testing a varistor ensures it functions correctly and can protect your circuit from voltage spikes. This article aims to demystify varistors by exploring their function, working principle, testing methods, and more. Start by touching the multimeter probes to the varistor's opposing leads. A functional varistor should show a multimeter. Test for open or short: On the multimeter, a good varistor should display an open. If it reads nearly infinite resistance, the varistor is still good. If it reads very low resistance, the varistor is blown. 3.how do you test for varistor? We’ll also discuss what to look out for when testing, as well as some potential troubleshooting techniques if something doesn’t seem right. This note details the common tests of varistor parameters and describes suitable test methods using simpli˜ed test circuits. In this article, we’ll cover the basics of testing a varistor and the tools you’ll need to do it correctly. The most common test for a varistor is the resistance test, measuring the device's ability to resist electrical current. All tests are performed at 25 o c, unless otherwise speci˜ed.
