Very useful in the HVAC/R Trade.
I used this tool to prevent major calls in the middle of the night. Its helps me generate sales to customers. I show them that their compresors, motors, transformers are about to go out, and most of them want to change the bad part with in a day or two. Of course, I had customers who have wished to listen to me.

Excellent Value
This meter enabled us to isolate and identify a defective appliance cord that was causing nuisance CAFCI trips. Isolation did not work, failures were minimum 4 days apart.
Moving the load stopped the failures (cord flexed differently). This is now a new weapon in our troubleshooting arsenal.
