I just sent my Snap On 5-75 ft lbs 3/8 drive to Team Torque in North Dakota for its annual calibration like I do every year. With the light use it sees (drain plugs, intakes, I mostly use it in the 18-50 ft lb range), its probably unnecessary to do it yearly but it gives me peace of mind. They called me back today, they said it was reading high on the low side of the scale, in the 15 to 16 pound range and that it would need to be adjusted and calibrated, and they wanted the ok from me to do it. they said they do see them reading high sometimes and that after adjusting it it should be fine. I was just puzzled in regards to the high reading as the wrench is never abused, always set back to 5 lbs after use and always wiped clean with a rag. they said they could tell I always turn it down after use and that I dont abuse it, as keeping the wrench dialed high would cause it to read high. Anyone ever ran into the same situation with a torque wrench that was well taken care of?
