Set transfer curve slope with span
A differential pressure transducer has a range of ±15 PSI with a 1-6 V
full READOUT SPAN of 3000 cannot be obtained during zero based span
adjustment. However, dividing both the READOUT SPAN and SWING
VOLTAGE by two, i.e. 1500 readout @ 2.5 V, allows the span adjustment
to be made for the proper transfer curve slope.
PAXLPV is to be calibrated to match a flow transducer whose output is 0
