CUST_UNIT
Table 6.1.2.5 - Available Unit Codes and Units
6.1.2.4
Customer Units
The CUST_UNIT multiplier in conjunction with UNIT_INDEX 99 allows the user to set their own units. The CUST_UNIT is a
multiplier times psi to achieve the customer’s unit value.
6.1.2.5
Calibration Adjustments
SPAN & ZERO - These are calibration multipliers and offset respectively. The zero is an offset applied to all output pressure values.
The span is a multiplier times all pressure output values..
