that repairs can be done by the Endress+Hauser service or specially trained customers.
Spare parts are contained in suitable kits. They contain the related replacement
instructions.

Endress+Hauser.

(XA) and certificates.

14.1.3
Replacement of an electronics module
If an electronics module has been replaced, it is not necessary to perform a new basic setup
as the calibration parameters are stored in the HistoROM which is located in the housing.
However, after exchanging the main electronics module it may be necessary to record a
new mapping (interference echo suppression).
14.1.4

Replacement of a device

After a complete device or electronic module has been replaced, the parameters can be
downloaded into the instrument again in one of the following ways:
• Via the display module
Condition: The configuration of the old device has been saved in the display module
→  169.
• Via FieldCare
Condition: The configuration of the old device has been saved to the computer via

You can continue to measure without carrying out a new setup. Only a linearization and a
tank map (interference echo suppression) have to be recorded again.
