To Mount Transducers on a 996PSP Pipe Simulator:
Using coupling compound, mount the transducers on the pipe simulator as shown on the
previous page. Slide each transducer until it presses against a pin-stop. Use the clamps to
hold the transducer in place.
Connect cables between each transducer and the computer connectors for the chan-
nel under test. The Up and Down orientation is not important.
Access the Installation Menu. Select [Meter Type] [Single, Dual, or Quad Channel] de-
pending on meter type. Select the meter channel (1,2,3, or 4) depending on which measure-
ment channel you intend to test. Select [Clamp-On] and then [Channel Setup].
Access [Channel/Path Setup] menu. Move highlight to [Create/Name Site]. Create a new
Site Setup (e.g., TEST1). You can now enter data without altering an existing Site Setup.
Select the [Pipe Data] Menu. Referencing either the English or metric pipe simulator
chart below, enter the pipe parameters corresponding to the transducer size under test.
Upon the completion of the [Install] procedure, the computer should report a sonic velo-
city within the range of approximately 1350m/s to 1700 m/s (depending on the transducer size
under test). Next, check the [Diagnostic Data] menu. The [Valc %] item must be >35 for
dependable operation. 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.
2.10.3 USING THE 996PSP PIPE SIMULATOR
Using the proper coupling compound, mount the transducers on the pipe simulator as shown
