b) Press and hold
Set
.
The current value flashes on the display.
c) Release
Set
when the value stops flashing.
The pressure transmitter displays the new value.
d) Press
Mode/Enter
.
The pressure transmitter sets the current system pressure as the end value
for the analog signal.
Manually scale the analog output
Follow these steps to manually set the start value (ASP) and end value (AEP) for the analog
output. The values for ASP and AEP must be within defined limits.
Procedure
1. Select ASP from the extended functions menu.
2. Press and hold Set to modify the parameter value.
3. Set the measured value at which the pressure transmitter provides 4 mA (20 mA if
OU2 = InEG ).
4. Select AEP from the extended functions menu.
5. Press and hold
Set
to modify the parameter value.
6. Set the measured value at which the pressure transmitter provides 20 mA (4 mA if
OU2 = InEG ).
Note
The minimum distance between
ASP
and
AEP
must be 25 percent of the upper
range limit (maximum rangedown is 4:1).
3.3.4 Optional settings
This section provides instructions for modifying optional settings. Modification of these
settings is not required for normal operation of the pressure transmitter.
Perform manual zero trim
Follow these steps to manually scale the pressure offset by +/-5 percent. Use this after
installation to trim out any measurement offsets because of mounting effects.
Procedure
1. Select
COF
from the extended functions menu.
2. Press and hold Set to modify the parameter value.
3. Set the value between
-5%
and
5%
.
The pressure transmitter modifies the measured pressure by this value.
