You check the cold pressure readings against the chart of ambient temp vs pressure range and adjust to the middle of the range using that one data point reference. Once set the pressure should reamin in spec throughout the cold range. If not the bi-metal strip may be worn out, damaged, or out of alignment.

Is the strip inside the WUR?
