A note on calibration dates:
Calibration dates are suggested by the manufacturer. You may overwrite the one year re-calibration date with an interval of your choosing, as long as this is documented in your Quality Manual or other quality documents. Atema recommends a 5 year re-calibration date for gages used as a Master set.
