For contact details see chapter 1 "General information" or the back page of
the operating instructions.
7.1 Maintenance
The thermometers described here are maintenance-free.
Repairs must only be carried out by the manufacturer.
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.
▶
Carry out the cleaning process as described below.
1. Prior to cleaning, disconnect the electrical connections properly.
2. Use the required protective equipment (depending on the application; the thermometer
itself is basically not dangerous).
3. Clean the instrument with a moist cloth.
This applies in particular to thermometers with a case made of plastic to ensure that any
risk of electrostatic charge is avoided.
Electrical connections must not come into contact with moisture!
CAUTION!
Damage to the instrument
Improper cleaning may lead to damage to the instrument!
▶
Do not use any aggressive cleaning agents.
▶
Do not use any hard or pointed objects for cleaning.
4. 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 skilled personnel 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 DKD/DAkkS is 100 mm.
