7.2 Environmental Compensation
When making adjustments, you can enter information about the environment in which you
perform the adjustment. This allows compensating for environmental factors that have an
effect on the measurement (for example, temperature, pressure, or background gases). The
selection of environmental compensations available in the Indigo calibration settings
depends on the features and configuration of the connected probe.
The environmental compensation selections are available on the Configuration tab of the
Calibration menu. To use environmental compensations, first enable the compensation from
the Measurement selections, and then enter the compensation in the Compensation
setpoints fields. You can also set the power-up default compensations that remain in use
also after probe reset.
