5-5.3 Field Test
This test performs internal ADFM system checks that should be performed
after installation. This test does the following.
•
Establishes communications and determines if the ADFM wake-
up message contains any errors. ADFM is “ready”.
•
Determines if the receive path is operating properly and returns a
Pass or Fail with an error. This test will fail if the transducer is
not connected to the electronics case.
•
Determines if the transmit path is operating properly and returns
a Pass or Fail with an error.
•
Determines if the electronics signal-processing path is operating
properly and returns a Pass or Fail with an error. This test will
