8. Maintenance, cleaning and calibration
▶
When cleaing from outside ("wash down"), observe the permissible temperature and
ingress protection.
▶ 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!
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 pointed and hard objects for cleaning.
▶
Wash or clean the dismounted instrument, in order to protect persons and the
environment from exposure to residual media.
8.3 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.
8.3.1 Instruments with removable measuring insert
(models Tx10-B, Tx10-C, Tx10-D, Tx10-F, TR10-J, Tx10-L, Tx10-0, TR11-C,
Tx12-B, Tx12-M, TR22-A, TR22-B, TR55, Tx81)
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.
8.3.2 Instruments with non-removable measuring insert or cable probes
(models Tx10-H, TR21-A, TR21-B, TR21-C, TR30, TR31, TR33, TR34, TR36,
Tx40, TR41, Tx50, Tx53, TR75)
The minimum length (metal part of the probe or the length of the probe below the process
connection) for carrying out a measurement accuracy test 3.1 or DKD/DAkkS is 100 mm.
8.3.3 Measuring inserts
(models Tx10-A, Tx10-K, TR11-A, Tx12-A)
The minimum length for carrying out a measurement accuracy test 3.1 or DKD/DAkkS is
100 mm.
