ADFM Test Procedures

Introduction
This chapter explains how to test the ADFM using BBTALK and the
WinADFM program. These tests thoroughly check the ADFM in a
laboratory environment, but are no substitute for a practice deployment.
You should test the ADFM:
• When you first receive the ADFM.
• Before each deployment or every six months.
• When you suspect instrument problems.
• After each deployment.
These test procedures assume all equipment is working. The tests can help
you isolate problems to a major functional area of the ADFM. For trouble-
shooting information, see
NOTE. The built-in tests require you to immerse the transducer faces in
water. If you do not, some of the tests may fail. Running the tests in air will
not harm the ADFM.
