Setting a damping for the analog signal
Damping the analog signal prevents the 4-20 mA output from erroneously changing
because of erratic pressure readings. The analog damping value is the response time in
seconds between pressure change and the change of the analog signal.
Procedure
1. Select dAA from the extended functions menu.
2. Press and hold Set to modify the parameter value.
3. Set a value between 0.01 and 99.99 seconds.
A value of 0.0 seconds deactivates damping.
4. Press
Mode/Enter
.
Perform a sensor trim
Follow these steps to perform a sensor trim and calibrate the pressure transmitter
measurement.
Procedure
1. Apply a defined reference pressure to the transmitter between ASP and AEP .
2. Select CAL from the menu.
3. Press
Set
.
The pressure transmitter displays CP1 .
4. Press and hold
Set
for five seconds.
The pressure transmitter displays the current pressure measurement.
5. Press Set until the pressure transmitter displays the reference pressure.
The pressure output can change by up to two percent of the upper range limit.
6. Press
Mode/Enter
.
The pressure transmitter displays CP1 .
7. Press
Mode/Enter
again.
The pressure transmitter displays CP2 .
8. To apply a second point on the curve or measured values, apply a second defined
reference pressure to the transmitter.
The minimum distance between the calibration points CP1 and CP2 is five percent
of the upper range limit.
9. Press and hold
Set
for five seconds.
The pressure transmitter displays the current pressure measurement.
10. Press Set until the pressure transmitter displays the reference pressure or the
corresponding analog signal is provided on OUT2.
The pressure output can change by up to two percent of the upper range limit.
11. Press Mode/Enter .
The pressure transmitter displays CP2 .
12. Press Mode/Enter again.
The pressure transmitter displays CAL .
