Damping Setup
Figure 13: Damping Setup Display
Use t e Type key to c ange t e Damping Type. T e options are a follows:
1) None. T e measured value is not filtered or damped.
2) Exp(exponential), w ic uses a traditional damping algorit m wit
response delays associated wit t e Damping Rate.
3) Smart, w ic employs a smart damping algorit m to produce and
instant response to a step c ange. After t e step c ange it uses t e
Damping Rate to damp t e measurement exactly as in exponential
damping.
Use t e arrow keys and t e Adaptive Interface W eel to set t e Damping
Rate in seconds. T e value can be adjusted between 0 and 32 seconds.
Press t e Exit key to return to t e main Pressure Sensor Setup menu.

Field Recalibration
Figure 1 : Field Recalibration Display
T e Field Recalibration Display contains t e following:
1. T e current calibration point and number of points displayed at t e
top.
2. Under “Apply:” in t e black ig lig ted area, t e nominal calibration
point in t e current pressure units for t e sensor is displayed.
3. Under “Range:” t e tolerance band around t e nominal value.
4. T e live pressure measurement in t e current pressure units is
displayed at t e bottom.
To run t e field recalibration procedure:
1. Apply t e pressure indicated in t e “Apply:” field. T e value must lie
wit in t e tolerance band indicated by “Range:”
2. Press t e Save key w en you are at t e correct input to calibrate.
T e live display value will s ow das es w en t e calibration point is
being saved.
3. Press t e Next key to advance to t e next calibration point. Repeat
steps 1&2 above.
4. Repeat steps 1-3 until you reac t e last point.
5. At t e last point t e Next key is replaced wit a Done key. W en you
ave finis ed calibrating t e last point press t e Done key.
6. A Calibration complete screen appears wit Exit and Save keys.
Press Exit to discard t e field recalibration. Press Save to store t e
