[GH85Carrera]

I had a circuit that I was trying to measure the precise impedance. A floor heater for a tile floor. The circuit kept throwing the ground fault breaker. I was lazy and grabbed a cheap analog Radio Shack meter that my dad had at his house and it showed everything as within tolerance. I scratched my head and used an analog meter that his neighbor had. It measured almost no resistance. OK, crap, I drove back to my place and while home called a buddy of mine that is more knowledgeable on electrical circuits. I grabbed my 25 year old digital Fluke and met my buddy with his meter. It was a better digital meter but just a home owner level meter. It read yet a third value and still within tolerance. I hooked up my Fluke and bingo, it showed too much impedance and the ground fault was doing the job as designed. No major surprise but that was not what we wanted to find out.

I have always preferred the right tool for the job. Over the years that Fluke has seem some hard service and it still works as designed.
