7.2 Cleaning
CAUTION!
Physical injuries and damage to property and the environment
Improper cleaning may lead to physical injuries and damage to property and
the environment. Residual media in the dismounted instrument can result in a
risk to persons, the environment and equipment.

▶ Prior to cleaning, properly disconnect the instrument.
▶ Use the required protective equipment (depending on the application; the thermometer
itself is basically not dangerous).
▶
Clean the instrument with a moist cloth.
This applies in particular to thermometers with a case made of plastic and cable probes
with plastic-insulated connecting cable, in order to ensure that any risk of electrostatic
charge is avoided.
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 (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.
