The pressure offsets on menus 7 and 8 and the temperature offsets on menus 9 correct the
controller's display of the parameters. The sensors used in these units have a high degree of
repeatability but may need initial correction (offset). An accurate pressure gauge or thermometer is
used to determine the correct temperature or pressure. A positive or negative offset value is then
entered to make the controller reading agree with the measured value.
