You can see the compensation values that are currently used by the probe by selecting them as display quantities from Main menu > Display > Quantities and Units. The quantities are as follows:
  • Tcomp: currently active temperature compensation value.
  • Pcomp: currently active pressure compensation value.
  • Ocomp: currently active oxygen concentration compensation value.
  • Hcomp: currently active relative humidity compensation value.

You can change the compensation settings from Main menu > Settings > Measurement settings.

When you turn a compensation off, the probe still shows a value for the corresponding display quantity (for example, Pcomp shows 1013.2 hPa). This is the default compensation value that is mathematically neutral for the probe’s internal compensation model.
GMP252 cannot receive the compensation values from a second probe connected to MI70. Only direct configuration is supported.
