120v solenoid coil resistance will vary depending on the model of the solenoid. Therefore, it is best to test an identical coil’s resistance. You could test a new solenoid or one that is working. You will become familiar with the resistances of coils in your facility over time. Should a Coil Have Continuity? Coils require …
There are many different ways to test a fuse without a multimeter. These include swapping, visual inspection, use of light bulbs, and more. Using a multimeter is typically the safest and easiest way to test a fuse but it’s not always an option. Swapping If another part of the equipment you are working on has …
Unfortunately, It isn’t possible to check phase rotation with a standard multimeter. Phase rotation must be checked with a specialized tester like the fluke 9040 or Amprobe PRM-6. These testers allow technicians to ensure equipment like pumps and compressors won’t be damaged by incorrect rotation. If you do not have access to a phase rotation …
Often when troubleshooting there comes a time to check the continuity of a wire. If both ends of the wire are close together this is a simple task. Just set your meter to continuity and put a lead on either end of the wire. Done. When the wire is already installed and the ends are …
Anyone involved in electrical maintenance needs to know how to check voltage on an outlet. In order to test this, you’ll need to use a multimeter or electrical tester. Because this test is done with the outlet energized make sure not to touch the metal part of the test leads to each other or to …
Testing voltage requires the use of a multimeter or electrical tester. Non-contact voltage testers can also be used but they are not as accurate as a quality meter. How to Check Voltage Some meters will autodetect if the voltage being measured is AC or DC. Other meters have different settings for alternating and direct current. …
Knowing how to test a blown fuse is an important skill for any electrician or maintenance technician. In this article, I’ll explain how to test a fuse using a digital multimeter. Fuses come in all shapes and sizes but luckily for us testing them is straight forward. Testing fuse continuity Checking a fuse for continuity …
