11.12Meter fingerprinting
The meter fingerprinting feature provides snapshots, or “fingerprints,” of twelve process variables, at four different points of transmitter operation. See Table

For all process variables except Mech Zero, the instantaneous value,
To use the meter fingerprinting feature:
1.From the ProLink menu, select Finger Print.
2.Use the Type pulldown list to specify the point in time for which you want to view data.
3.Use the Units pulldown list to specify SI or English units.
The display is updated continuously.
Note: Due to the continuous updating, the meter fingerprinting feature can have a negative effect on other
11.13Troubleshooting filling problems
If the fill cannot be started:
•Check the status LED on the transmitter.
-If it is solid red, the transmitter is in a fault condition and a fill cannot be started. Correct the fault condition and retry. The cleaning function may be useful.
-If it is solid yellow, the transmitter is in a
Note: A fill can be started under some
If the system is in slug flow, try using the cleaning function, or pulsing fluid through the sensor by turning the discrete outputs ON and OFF (if the valves are controlled by discrete outputs). The Test Discrete Output function can be used for this.
•Ensure that the fill is correctly and completely configured:
-A flow source must be specified.
-A
-All outputs required for valve control must be configured.
