Precision pressure transducers are characterized to 32 numeric points at the factory to determine
offset, linearity, repeatability, and hysteresis. The 32 points of characterization are unique to each
transducer and referred to as ‘Transducer Coefficients’. When replacing a transducer for any
reason, the coefficients must be reloaded with the proper coefficients for the replacement
transducer.
