Notes for T Adjustment

Temperature adjustment is always a simple 1-point offset correction.

Notes for RH Adjustment

1-point humidity adjustment affects both offset and gain, depending on
the adjustment condition. In a dry condition (for example, 11 %RH),
offset is adjusted more than gain.
The 1-point humidity adjustment requires that the target condition is at
least 50% of the currently measured value. This prevents the user from
making excessive corrections that are very unlikely to be needed.
