SET FAIL LEVEL Mode
(off, 4 mA or 20 mA)
. Use
arrow keys
to set the value
at which 20 mA is desired, and press
ENTER key
to
enter it.
NOTE:
If the same values are set for 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 analog output signal. A minimum value of “0 sec-
onds” has no smoothing effect. A maximum value of “60
seconds” provides maximum smoothing. Deciding what out-
put filter time to use is a compromise. The higher the filter
time, the longer the analog output signal response time will
be to a change in the measured value.
