Wow, glad I asked!!!!
I always for tx/rx wires, kept it around 450 ish"...but than again was not sure if tip /dial was accurate, I have a couple high end FLUKE meters that I use at for work, which do have the temp option on meters....instead of silly gun, I did a comparison , with my 999$ Fluke Ti100 infrared meter,The only reason I mention the price, as its extremely accurate and some might look up, and say use that for sure don't need nitro on screen , and banging around, etc..., lol, breaking in motor?? Sure, Why not?>>
But that would be about the only time i pull the Ti100 Beast out!!! For when I use, it's generally to look into 200amp BREAKERS, 20 HP Chiller motors, centrifugal pumps.etc etc etc.....ok way to much, sorry,.,.,
The Test was my Fluke Meters , and several Fluke Probes, VS.. and Old Exergen , well she was quite a bit was older.
But still, they used to be the go to temp guns, not sure what people use now-a-days, but I had a sliding scale 0-90 degrees being too high, or too low, than I plugged into my 902FC , which is a great meter, same result, than the 117 again, the Fluke meters were all around 1-4 DEGREES APART...Maybe it's time to re-calibrate Exergen?
If I even can get re-calibrated, as it has been sitting around a while, REAL long, I forgot I had it,NO B.S.!!
till I was doing a garage cleaning..Hidden Treasure, Found Lots of Awesome R/C Parts/even Cars ,lol, I forgot about, like mini's....


anyway thanks,
and I'm assuming the Exergen still holds the Chariot of fire,haha, I looked up still for sale? sooo, not discontinued red it a awesome sign, only fluke meter I know like that is the ol trusty T87,they call it different things now, t87-t etc, all sorts of variations, so they get EVERYONES MONEY!!...LOL.
Still have mine and calibrate every 2 years for past 23 years!!, its GRAY, ever see a GREY Fluke?
