Recalibrating the CT440
Some calibration steps require the adjustment of internal optical components.
The calibration validity period depends on the intensity of use and environmental
conditions. You can determine the adequate calibration interval for your CT440 according
to your accuracy requirements.
Under normal conditions of use, we recommend to perform a factory recalibration of the
CT440 after one year of normal use.
