Calibration Error Messages

Calibration Error Codes:

   
  1. The correct white calibration standard must be used.

    Specifically, each instrument is "married" to a particular calibration plaque at the X-Rite factory. The absolute reflectance values of this plaque are programmed into the instrument's RAM memory as it undergoes final testing. Each plaque is serialized and the serial number of its matching instrument is hand-written on the protective envelope. The use of an alternative plaque may well fool the instrument into thinking that the ceramic surface has changed.
