Notes:
1. Offsets are used to fine-tune certain readings generated by sensors. For example, if the controller was
showing a 125 psi value and a calibrated pressure gauge at the same location showed 127 psi, an offset of
+2 psi would be entered and the controller would then read the corrected value of 127 psi.
