Cleaning the enclosure
● Clean the outside of the enclosure with the inscriptions and the display window using a cloth moistened with water or a
mild detergent.
● Do not use any aggressive cleansing agents or solvents, e.g. acetone. Plastic parts or the painted surface could be
damaged. The inscriptions could become unreadable.
WARNING

dry cloth.
Prevent electrostatic charging in hazardous areas.

Recalibration procedure
Loosen recessed grip screw(s) to remove the RTD connector or
housing and unscrew the measuring insert from the pipe collar.
Use calibrator sleeves that have been adapted to the shape of the
RTD unit only.
Insert must have a borehole of ∅6.00 mm (0.24") H7, depth = 8 mm
(0.31").
Do not exceed 100 °C (212 °F) at locking plug [80 °C (176 °F) when
using a temperature transmitter].
Use block calibrator with dual-zone-technology with internal
reference sensor only.
Observe the adjustment time specified by the manufacturer when
heating the calibrator.

Apply heat sink compound to the RTD unit before inserting it
in the calibrator sleeve.
Check the electrical connector (cable end) as indicated by
the nameplate.
After inserting the RTD unit, wait about 5 minutes for the
temperature to settle.
Compare the temperature of the calibrator with the RTD
