ADFM Test Procedures
5-1 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
Chapter 6 .
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.
5-2 Test Setup
Use the following steps to connect the ADFM system and to place the
ADFM in a known state.
a. Connect a laptop computer to the RS-232 communication port.
b. Connect and apply power to the system as described in Chapter 2 .
c. Place the ADFM transducer in approximately one foot of water.
