Interaction between mA Output Cutoff and process variable
cutoffs
When mA Output Process Variable is set to a flow variable (for example, mass flow rate or
volume flow rate), mA Output Cutoff interacts with Mass Flow Cutoff or Volume Flow
Cutoff. The transmitter puts the cutoff into effect at the highest flow rate at which a cutoff
is applicable.

Overview
mA Output Damping controls the amount of damping that will be applied to the mA
output.
Damping is used to smooth out small, rapid fluctuations in process measurement. The
damping value specifies the time period, in seconds, over which the transmitter will spread
changes in the process variable. At the end of the interval, the value reported by the mA
output will reflect 63% of the change in the actual measured value.
mA Output Damping affects a process variable only when it is reported via the mA output.
If the process variable is read from the display or digitally, mA Output Damping is not
applied.
Procedure
Set mA Output Damping to the desired value.
• Default: 0.0 seconds
• Range: 0.0 to 440 seconds
Tips
• 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 the process variable
assigned to the mA output 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.
