I recently had my zareba 5 mile charger repaired at your Washington location so iknow it works. however when I tested it with the RSVT8 tester the lights didn't light. so I had it checked at a hardware store and was told it was working but the lights weren't. so I returned it and got a replacement. the same thing is happening. is this the right tester for this model charger?
Question by: joan bowman on Feb 26, 2018, 7:00 PM
The lights on this tester can sometimes be hard to see. We recommend sheltering the tester from the sun. Also, shining a flashlight onto the tester works well to illuminate the lights.

Why is there no accuracy range of the voltage in specification of this tester..? My fence energizer states a specification of 5,000 volts max at zero ohm load at energizer terminals, and yet this tester states 7,000 volts.
Question by: Bob on Sep 11, 2018, 8:00 PM
The energizer's no load voltage will fluctuate +/- 20%. If all the lights on the tester are illuminated during a no load test, that is showing the energizer has a great output and is working correctly.

So I tried out the new 8light tester put the ground wire in the ground an touched the fence and all 8 lights started flashing and flashed with each pulse of power coming from the controller.. what does this mean... I know the fence works the dog bumped it and yelped... would like to know how ,any volts it shooting.
Question by: Roy on Oct 27, 2020, 8:00 PM
This would indicate that the fence is testing at 7,000 volts.
