Pressure Transducer Gain (Fast Fill & Temperature Compensated Units Only)
The pressure transducer gain (GAinA, GAinb, GAinA2 and
GAinb2) is a correction factor used to ensure the pressure transducer is
correctly calibrated. Typical values for the gain are usually close to
0.4000.
GAinA and GAinA2 relate to the gains of pressure transducers one
and two (where fitted) on side A of the dispenser.
GAinb and GAinb2 relate to the gains of pressure transducers one
and two (where fitted) on side B of the dispenser.
The pressure transducer gain is set during the calibration phase and does
not require adjusting during service
