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 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
When changing operating parameters in the function groups
analogue inputs and display/measurement range always check
for possible effects on other function groups.
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 11.
5.1 Analogue input
The universal measurement input is set up in this function
group. After entry of the input signal/sensor type additional
addresses for further description of the input are displayed.
When using RT s the type of connection as well as the cable
resistance must be entered, on thermocouple inputs the type of
cold junction compensation as well as temperature must be
entered. The measured value display engineering units must be
entered for both types.
If the linearisation table is to be used then the measurement
range of the connected sensor must be entered in this function
group. The actual table is set up later.
