How often should we calibrate the equipment?

The frequency of the calibration of equipment depends on several factors:

  • If the equipment is or is not likely to change its characteristics over time;
  • If it is a device whose behaviour is not known, the calibration period should be shorter;
  • If the equipment has historically, in previous calibrations, not presented good reproducibility;
  • If it is subject to any standard or procedure which specifically indicates the frequency of calibration.
