Preparing the temperature calibration
To determine the exact measured value of the integrated temperature sensor, a temperature
comparison measurement has to be performed every three months.
If a major temperature deviation is found during this check, a temperature calibration is required.
During this process, the temperature control of the device is set to the value measured during the
temperature comparison measurement.
Use a calibrated measuring instrument with an accuracy of ± 0.1 °C for this test. To minimize
temporary temperature fluctuations during the measurement, the measuring instrument is placed
into the work space in an isothermal container (e.g. a bowl filled with glycerol). The center of the
work space is the reference location for the comparison measurement.
NOTE!
Isothermal container:
Do not use a container filled with water as an isothermal container as the evaporation of water will
result in a lower temperature reading!
