Calibration Interval; Technical Data - Unitest Therm 200 Bedienungsanleitung

6.3 Calibration Interval

We suggest a calibration interval of one year. If the instrument
is used very often or if it is used under rough conditions we
recommend shorter intervals. If the instrument is used few
times only the calibration interval can be extended on to 3
years.
