7.10 Changing Environmental
Compensation Settings with Indigo
The configuration options in Indigo transmitters include probe-specific settings that vary
depending on the features of the connected probe.
In the case of Vaisala CARBOCAPâ Carbon Dioxide Probes GMP251 and GMP252, the probe-
specific settings allow configuring the filtering factor and environmental compensations.
To change the environmental compensation settings:
1. Launch the Indigo wireless configuration interface and open the Settings > Probe
menu. 
2. Enable the required environmental compensations (set the compensation On or 
O)
you need to use in the Measurement selections. For temperature compensation, select
either the measurement from the probe sensor (Measured), or manual Setpoint entry.
3. Enter the setpoint values for the compensations you have enabled into the
Compensation setpoints text fields. 
The values entered into the Compensation setpoints 
fields are only for temporary
use: when you reset the probe, the default values (see Compensation power-up 
defaults) are restored.
