As I have said previously, without a calibration jig, the TM1 is of limited utility.
Not having the sheet in front of me, that sounds like about one marking on the TM-1, right?
And it sounds like you've calibrated this tool multiple times. Does it regularly (like almost every time you check it) read about a marking high?
