11. 9 Endress+Hauser parameters:
Transducer Block "Service"
All the parameters required for service purposes are located in the Transducer Block "Service" (base
index 900). As these parameters affect the accuracy and the functionality of the device, changes may
only be carried out by Endress+Hauser service technicians. The parameters of the Transducer Block
"Service" are not described in these Operating Instructions  Please refer to the special Service
Manual.
11. 10 Analog Input Function Block
In the Analog Input Function Block, the process variables of the Transducer Blocks "Flow" and
"Totalizer" are prepared for subsequent automation functions (e.g. scaling and limit value
processing). The automation function is defined by connecting up the outputs.
