7.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.
8.Check the [Xdcr Mount Mode] menu cell. Adjust to match the simulator chart above.
9.Move the highlight down to [Install Completed?] by pressing . Access the option list. To move
the cursor to [Install] press . PressENT to start the transducer install routine.
NOTE: Since Sizes A and C transducers are installed in Reflect Mode, you will see a
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] 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 than 2% of the published Vf max.
Confirming these values certifies that the entire system (computer, transducers, cables) is operating correctly. The investigation should proceed to a review of all site conditions to locate the operating problem.
