Did you get the Fluker's digital from Petsmart? I had, like, 4 of those and they all pooped out after a very short time.
It says that accuracy is guaranteed and does not recommend calibration. The people at the store told me that if I ever had issues with accuracy, to bring it back, and it would be repaired or replaced.
The way that I plan on doing it is to get a cheap analog gauge, calibrating that, and putting that in the 'tat to test the other one (to see if it matches up w/ the calibrated one).
I really like it, it really is by far the most accurate gauge I've ever had... and it better be considering how much I paid for it.
It's so worth it though, because then I don't have to keep buying gauges over and over that are never accurate.
