9.3 Calibration, recalibration
It is recommended that the measuring insert is recalibrated at regular intervals (resistance
thermometers: approx. 24 months, thermocouples: approx. 12 months). This period can
reduce, depending on the particular application. The calibration can be carried out by the
manufacturer, as well as on-site by qualified technical staff with calibration instruments.
For calibration, the measuring insert is removed from the thermometer. The minimum length
(metal part of the probe) for carrying out a measurement accuracy test 3.1 or DAkkS is
100 mm [3.94 in].
Calibration of shorter lengths on request.
