HQRP 3 Phase Sequence Rotation Tester LED Indicator Detector Checker

Very good product for purpose. If you are an electrician who does a lot of 3 phase motor hook ups this is a good time saver. you can check rotation by clipping to in put power at starter. check indicated rotation on meter against desired rotation of motor. if they match you connect your motor as is.If the rotation is backwards you swap two motor T leads and terminate. Saves you the trouble of making connections improperly and operating motor in reverse. (possibly damaging pump or compressor.) Then having to remake all our connections correctly. Pros: Carry case. Easy to use. Obvious indication of rotation. Cons: Color of leads may make beginner think green lead goes to ground. (just hook up by letter.) Why include the UV detectors. I wasted more time trying to figure out when I would use these, and why they were included. Ok, not really a con.

Perfect! Thanks!
