*The flow computer generates the Number Index.

**See note below.

NOTE: When using a 996PS-4 Simulator, you must access the [Application Data] menu, select [Liquid Type] - [Other], then program the [Estimated Vs] for a value of 2100 m/s.

6.Access the [Pick/Install Xdcr] menu. Access the [Transducer Model] menu cell. Enter the Trans- ducer Model option list. Select [991 Universal].

7.Check the [Transducer Size] menu cell. If necessary, enter the Transducer Size option list and pick the actual transducer under test.

8.Check the [Xdcr Mount Mode] menu cell. Adjust as necessary to match the simulator chart above.

9.Move the highlight down to [Install Completed?]. Access the option list. Move the cursor to [Install]. Press <ENT> to start the transducer install routine.

10.Check to make sure that the flow computer returns the Number Index listed in the chart above. Next, review and verify the Diagnostics data items as described previously. If the computer, cables and transducers are operating properly, then review all site conditions to locate the operating prob- lem.

If a Pipe Simulator/Test-Block Test Fails:

1.Replace the transducer cables. If this allows you to complete the test as described above, then the cables were defective.

2.If the cables are proven to be good, replace the transducers on the pipe simulator with a “known good” set. If the system functions properly, then the original transducers under test are defective. Please return any defective transducers to Siemens for repair.

3.If you replace the transducers and cables, and the system still fails to function correctly, then it is likely that the computer has a malfunctioning circuit module. If you have spare modules you may try module substitution to identify the defective module. Otherwise, please call our Technical Service Department for further instructions.
