Use the required protective equipment (depending on the application;
the thermometer itself is basically not dangerous).

Clean the instrument with a moist cloth. Electrical connections must
not come into contact with moisture!

Wash or clean the dismounted instrument, in order to protect persons
and the environment from exposure to residual media.
7.3 Calibration, recalibration
It is recommended that the measuring insert is recalibrated at regular
intervals of approx. 24 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 skilled personnel with
calibration instruments.
In line with the intended use of a pipe-mounted probe, the testing should
be carried out on controlled, heated reference surface (dry calibration).
