Tip
• A high damping value makes the process variable appear smoother because the reported value changes
slowly.
• A low damping value makes the process variable appear more erratic because the reported value changes
more quickly.
• The combination of a high damping value and rapid, large changes in temperature can result in increased
measurement error.
• Whenever the damping value is non-zero, the damped value will lag the actual measurement because the
damped value is being averaged over time.
• In general, lower damping values are preferable because there is less chance of data loss, and less lag time
between the actual measurement and the damped value.
Effect of Temperature Damping on process measurement
Temperature Damping affects all processes and algorithms that use temperature data from the internal
sensor RTD.
Temperature compensation
Temperature compensation adjusts process measurement to compensate for the effect of temperature on
the sensor tubes.
API referral
Temperature Damping affects API referral process variables only if the transmitter is configured to use
temperature data from the sensor. If an external temperature value is used for API referral, Temperature
Damping does not affect API referral process variables.
Concentration measurement
Temperature Damping affects concentration measurement process variables only if the transmitter is
configured to use temperature data from the sensor. If an external temperature value is used for
concentration measurement, Temperature Damping does not affect concentration measurement process
variables.

Pressure Measurement Unit controls the measurement unit used for pressure. This unit must match the unit
used by the external pressure device.
Pressure data is used for pressure compensation and for API referral. The device does not measure pressure
directly. You must set up a pressure input.
Procedure
Set Pressure Measurement Unit to the desired unit.
