Troubleshooting continued
Checking the calibration factors
Check or change the flow, density, or temperature calibration factors at
the transmitter. The temperature cal factor is for the RFT9739, Model
1700, Model 2700, Model 3500, and 3700 only. If necessary, refer to the
instruction manual (or on-line help for software) for the method you
choose.
• Use the Model 3500 or 3700 display
• Use a HART Communicator, ProLink or ProLink II software, or AMS
software
• Use the host controller
Enter the calibration factors that are listed on the flowmeter calibration
tag. (Calibration factors are also listed on the certificate that was
shipped with the meter.) If the calibration factors at the flowmeter are
already correct, the problem is not with the calibration factors.
Checking the damping value
Check or change the damping value at the transmitter. If necessary,
refer to the instruction manual (or on-line help for software) for the
method you choose.
• Use the Model 3500 or 3700 display
• Use a HART Communicator, ProLink software, or AMS software
• Use the host controller
In almost all applications, the damping value should be greater than or
equal to 0.8 seconds. If the damping value is already greater than or
equal to 0.8 seconds, the problem is probably not with the damping
value.
Damping values less than 0.8 seconds are used in very few applications.
After troubleshooting is complete, if you have a question about whether
your application might require a lower damping value, contact the Micro
Motion Customer Service Department. Phone numbers are listed on
page 41. The two most common applications affected by a damping
value that is too high are:
• Very short batching applications
• Very short-pass proving applications
Checking the drive gain
Contact Micro Motion to check the drive gain. Phone numbers are listed
on page 41.
If the transmitter is a Model 1700, 2700, 3500, or 3700, you can use the
display to view drive gain. For more information, refer to the manual that
is shipped with the transmitter.
Checking the density or temperature reading
View the flowmeter density or temperature measurement in any of
several ways:
• Use the transmitter display, if it has one
• Use a HART Communicator, ProLink or ProLink II software, or AMS
software
• Use the connected output device, if there is one
