A tab with hardware and software information for each correctly installed option-

Inputs/Outputs
Depending on the type of input, up to 2 columns will be visible in the Device Info
screens for inputs.
•
Compensated: Display value that is calculated from the value measured by
the sensor through use of an appropriate compensation method and after
taking the corresponding calibration values into account.
This suppresses incorrect measuring values that can be caused by outside
factors (e.g. temperature) or sensor wear (e.g. a dirty electrode).
• Uncompensated: Value measured by sensor (raw value of the measure-
ment input, e.g. pH measuring chain voltage)
These sensor values are subject to distortion caused by outside factors.
