idk, but ive sent everyone of them back and they have told me that is was the probes fault, and the last time they sent me both a new gauge and probe, now its jus reading way to cool, no way after romping and stopin on it can the temps come down to 150 degrees before i can even get to a stop,lol
i dunno what i would have done wrong, ive checked everything, cus thats what i thought also.
id take any suggestions autometers are exspensive,lol
