6. Access the [Pick/Install Xdcr] menu. Check the [Transducer Size] menu cell. If necessary, enter the
Xdcr Size option list and pick the transducer under test.
7. Check the [Xdcr Mount Mode] menu cell. Adjust to match the simulator chart above.
8. Move the highlight down to [Install Completed?]. Access the option list. Move the cursor to [Install].
Press <ENT> to start the transducer install routine.
NOTE: Since Sizes A and C transducers are installed in Reflect Mode, you will see a pop-up
window that prompts you to: [Use Actual Zero]. You can ignore this by pressing the
<Down Arrow>.
Upon the completion of the [Install] procedure, the flow computer should report a sonic velocity within
the range of approximately 1350m/s to 1700 m/s (depending on the transducer size under test). Next,
check [Diagnostic Data/Flow Data] menu. The [Valc %] item must be >35 for dependable operation. In
addition, note the reading, then compare it to the [Vfmax] item in the [Diagnostic Data/Site Setup
Data] menu. The value of the reading should be less that 2% of the published Vf max. Confirming these
values certifies that the entire system (computer, transducers, cables) is operating correctly. The inves-
tigation should proceed to a review of all site conditions to locate the operating problem.
