AMS Device Manager
1. Right click on the device and select Configure.
2. In the left navigation pane choose Manual Setup and choose the Sensor 1 or Sensor 2 tab
depending on the need.
3. Find the Transmitter Sensor Matching (CVD) group box and enter in the required CVD constants. Or
select “Set CVD Coefficients” button to be guided through steps. You may also select “Show CVD
Coefficients” button to see the current coefficients loaded into the device.
4. Select Apply when complete.
Note
When the transmitter-senor matching is disabled, the transmitter reverts to either user or factory trim,
whichever was used previously. Make certain the transmitter engineering units default correctly before
placing the transmitter into service.
5.7 Switching HART Revision
Some systems are not capable of communicating with HART Revision 7 devices. The following
procedures list how to change HART revisions between HART Revision 7 and HART Revision 5.
5.7.1 Generic menu
If the HART configuration tool is not capable of communicating with a HART Revision 7 device, it should
load a Generic Menu with limited capability. The following procedures allow for switching between HART
Revision 7 and HART Revision 5 from a generic menu in any HART compliant configuration tool.
1. Locate “Message” field.
a. To change to HART Revision 5, Enter: HART5 in the message field.
b. To change to HART Revision 7, Enter: HART7 in the message field.
5.7.2 Field Communicator
From the HOME screen, enter the Fast Key sequence and follow steps within the Field Communicator to
complete the HART revision change.
5.7.3 AMS Device Manager
1. Right click on the device and select Configure.
2. In the left navigation pane choose Manual Setup and click on the HART tab.
3. Select the Change HART Revision button and follow the prompts.
Note
HART Revision 7 is only compatible with AMS Device Manager 10.5, and greater. AMS Device Manager
version 10.5 requires a software patch to be compatible.
