to set the displayed
value at which 20 mA is desired, and press

to enter the value.
NOTE:
If the same values are set for 0/4 mA and 20 mA, the
output automatically goes to, and remains at, 20 mA.
A time constant (in seconds) can be set to filter or “smooth
out” the output signal. A minimum value of “0 seconds” has
no smoothing effect. A maximum value of “60 seconds” pro-
vides maximum smoothing. Deciding what output filter time
to use is a compromise. The higher the filter time, the longer
the output signal response time will be to a change in the
measured value.
