How to fix 'Cannot calibrate' error on OHAUS Scales?
- E
  Eileen BakerAug 13, 2025
  If the OHAUS Scales display 'Cannot calibrate', first ensure that the Calibration Menu is not locked; if it is, turn the Calibration menu lock off. Also, check if LFT is turned on; if so, turn LFT off. An unstable environment can also prevent calibration, so move the balance to a more suitable location. Finally, verify that you are using the correct calibration masses; if not, use the correct ones.
