Most of the time, the testers will handle frequencies that are between 15 Hz and 400 Hz. You will want to know the specifications of the types of motors and pumps that you will be testing, so you can make sure the motor winding testers that you choose will work with those items before you rent.

One of the mistakes that some people make is to use just an ohmmeter. While this can show if the windings are good or bad, it does not have the ability to let you know whether there are potential failures in the future.

​The motor winding testers tend to be relatively easy to use. However, it should still only be used by those who know how to utilize the tester and read and understand the results. When you are choosing one of these items, make sure you check to see what types of features it offers. There are three phase rotation meters that are quite helpful.

These will have three test leads that you can use. This will help to determine the phase order and avoid wiring incorrectly. They can check for phase loss, and determine the rotation direction of the motor.
 

In the past, it could be extremely difficult to test the windings in a motor, but this device makes the process much simpler, not to mention faster. The motor winding testers available can take the guesswork out of testing motor windings, and it can save a substantial amount of time and frustration. Of course, you need to be sure you are getting a tester that will work well for your needs.

A motor winding tester, or a phase rotation meter, is an item that is used to help detect motor faults that other instruments cannot find. These are often used on motors and pumps before installation. The tester will let you know if the pump or motor is in good condition so you do not install it only to find out later that it is no good. It is also used for monitoring the motors that are already installed, and it can find issues and show you any problems that might be developing.

You can find a range of manufacturers in the market today that offer these motor winding testers. Some of the options available include Davis Instruments, Motor Diagnostic Systems, and ABQ Industrial.
