Adjusting the analog input
The input can be adjusted to the sensor with the aid of the following parameters.
For current, voltage and resistance sensors, a scaled value is calculated from the sensor
signal.
For temperature outputs, the scaled value is calculated from linearization tables. The
temperature value can be converted to degrees Celsius, degrees Fahrenheit or Kelvin. In
addition, the temperature value can be corrected by means of an offset.
6.3.2 Display - DISPLAY/M2
All of the display settings are grouped under this menu item.
The signal types 4 to 20 mA, thermocouples and resistance thermometers are
monitored for cable open circuit. Long reaction times can occur in the case of
resistance thermometers.

Parameter setting Description
Ref. num. Input
Lin. table
Total (*)
Inp.+Lint.
Inp.+Tot. (*)
Lint.+Tot. (*)
In+Lin+Tot (*)
Batch (*)
For choosing the display value on the display.
(If a combination is selected, e.g. "Inp.+Lint", the display
alternates between the selected display values, e.g.
measured value (Inp.) and linearized measured value
(Lint.))
• Input = measured value
• Lin. table = linearized measured value or current
flow rate for calculation of channel
• Total = integrated value
• Inp.+Lint. = alternates between measured value and
linearized measured value
• Inp.+Tot. = alternates between measured value and
integrated value
• Lint.+Tot. = alternates between linearized measured
value and integrated value
• In+Lin+Tot = measured value, linearized measured
value or integrated value
• Batch = preset counter
Settings marked with an asterisk (*) are only available
if the pulse output or integration option is available
and has been configured
Display sw. 0 to 99 sec
0
Selectable period for displaying the individual values if
combinations of display values have been selected
under Ref. num.
This setting is only available if the pulse output or
integration option is available and has been configured
