display. This function offers settings through which you can alter values
obtained from the sensors before display or recording. This functionality
is generally used to make sure that the displayed and recorded values
match those of a reference measurement or instrument. The most often
used example of this concerns absolute and relative pressure
measurements.
All calibration settings generally offer an OFFSET, or FACTOR
(COEFFICIENT). A recorded and displayed value is computed from
the sensor value by multiplying the sensor value by the FACTOR and
then adding the OFFSET. Where factors are not offered as a setting, the
factor will be 1. This will also be the default factor. The default offset will
be 0. Frequently only barometric settings will need adjustment!
While changing a setting, the console displays what the current sensor
value is with this offset or factor applied so you can either determine
desired offset beforehand, know what you reference value is and
manipulate offset until the reference value is matched.

key to enter the following sub-setting:
1) IN TEMP OFFSET: Offset for indoor temperature.
2) IN HUMI OFFSET: Offset for indoor humidity.
3) OUT TEMP OFFSET: Offset for outdoor temperature.
