There is no need, nor is it possible, to perform a manual self test with the 475 Field

Communicator. Testing features are done automatically. A warning message appears if a fault condition is found during these tests.

It is not necessary or possible to calibrate the 475 Field Communicator. The 475 Field

Communicator is a communication interface that communicates digitally with HART and F OUNDATION fieldbus devices.

Voltage measurements made by the 475 Field Communicator are for use in detection of power or noise on a network, and are for reference purposes only. NIST standards are not applicable to the 475 Field Communicator.
