5.3.8 Correction values for measuring points
If the measured value of a sensor deviates from the actual value, it can be compensated with a correction value.
• In the menu path: "Selection 2/2" -> "System" -> "Correction values" select the correction parameter (see Fig 5-9) and
modify values Tab. 5-4 accordingly.
