Operation
During device operation, take care that the device remains within its intended temperature
range. No other monitoring is necessary.
Permissible media temperature:
-
40…150 °C
Permissible ambient temperature:
-
20…80 °C
4.1 Calibration
We recommend an annual recalibration.
Uninstall only the measuring insert. This way the measuring position remains unchanged
as it is defined by the clamping element.
Apply new heat conductive paste when you reinstall the measuring insert after the calibra-
tion. This ensures a good and constant thermal coupling between insert and pipe.
For further details please consult the separate calibration guideline for the Clamp-on family
(TA_008).
4.2 Maintenance / Service
When properly installed in accordance with applicable specifications, this device is
maintenance-free. However, we recommend an annual recalibration of the device.
In case of damage or defects, the customer can replace the following elements:
Display module
Cable glands (if applicable)
Clamping element
For defects to other components, repairs must be performed in the factory.

Disassembly
When measuring hot media, make sure that the device has cooled down prior to any dis-
mounting or wear appropriate protective clothing to avoid burns.
Switch off the power supply to the device before disconnecting the electrical connections.
Once this is done, the device may be mechanically removed.
