5. Operating parameter description
This chapter describes all setting up parameters of the unit with each
range and default settings. Unit parameters can be directly set up or
changed without the need for any further tools if the unit is ordered with
the LC display and front end operation option. All parameters can be
easily changed using the serial interface and the PC operating software.
Once parameters have been changed please check the effect this has on
other parameters.
The addresses identified by * as well as “Possible settings” are only
available depending on the previously set up parameter or the options
released. The following listing shows the maximum possibilities.
For documentation purposes the actual settings can be written down in
the parameter list found in chapter 9.
5.1 Analogue inputs
The measurement inputs are set up in this function group.
If the linearisation table is being used then the measurement range of the
connected sensor must be entered in this function group. The
linearisation table is set up later.
The 2nd analogue input is available dependent on the
selected unit model.
