## Questions & Answers

**Q: How could you use this to test a 50 amp plug in for an RV at campgrounds - use an adapter changing the 110 to 50 and if so does that work?**
A: The unit only tests for the existance of 60Hz power on a particular wire
Amps don't matter
A 50 Amp plug is 240v
It has 2 hot lines at 120v each and 1 neutral and 1 ground
Sometimes neutral and ground are the same with only 3 blades
on the plug
Anyway, bringing the tester near the outlet will tell you if it's live
it won't tell you if there is a problem like one hot line being out or
low voltage on either leg
You would need a multi-meter and some training to do anything else
A good poor man's tester is an old fasioned lightbulb 60w across one
hot leg and neutral then the other hot leg and neutral
If the brightness is the same for both then you're good

**Q: What does a reading of flashing red light indicate when plugged into a replaced gfi outlet? a green light indicated "correct"  wiring. two other outle**
A: The gfi is not working or the gfi is faulty to begin with.

**Q: Downloaded the operating instructions, but still cannot figure out how to install the lr44 battery?**
A: Hello, 
Thanks for your inquiry. On the backside of the tester there should be a polarity indicator on the tester and on the inside of the battery compartment.

**Q: can you use this for break point testing of wires?**
A: It is designed for live wire break point testing, but this isn't a TDR.  (time domain retroreflector)  
It is a very high quality device, that is prices remarkably low.
I keep this in my go toolbag and find its very rugged and convenient.
