instructions.
All the spare parts kits which you can order from Endress+Hauser for repairs are listed

After a complete instrument or electronic module has been replaced, the parameters
can be downloaded into the instrument again via the communication interface.
Prerequisite to this is that the data were uploaded to the PC beforehand using the
ToF Tool / Commuwin II. Measurement can continue without having to carry out a new
setup. Only a linearisation and a tank map (interference echo suppression) have to be
recorded again.
