Adaptive the time constant is changed dynamically so that the transmitter can respond rapidly to actual changes in signal while filtering out random noise The moving average filter is reset to the latest reading when the accumulated difference between individual readings and the filtered reading exceeds a Threshold The accumulated difference is also reset to zero when the latest reading has a different polarity than the filtered reading With Conventional filtering the adaptive feature is disabled and the Time Constant does not change e Threshold allows selection of Low Adaptive or High Adaptive for the Adaptive filter selection Normally select Low Select High if the signal has large spurious transients which should not be considered as an actual change in signal Peak Valley Filter allows the peak maximum or valley minimum functions to be based on Unfiltered or Filtered readings Normally select Unfiltered Select Filtered if you expect spurious readings which you do not wish to capture 32 17 TRANSMITTER CALIBRATION All analog input and analog output ranges of the transmitter have been digitally calibrated at the factory prior to shipment using calibration equipment certified to NIST standards Calibration constants are stored digitally in non volatile memory in EEPROM on the signal conditioner board and main board This allows signal conditioner boards to be changed without requiring transmitter recalibration If periodic rec
