<Down Arrow>.
Upon the completion of the [Install] procedure, the 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 the [Diagnostic Data] menu. The [Valc %] item must be >35 for dependable operation. In
addition, note the reading, then compare it to the [Vf max] 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 investigation should proceed to a review of all site conditions to locate the operating problem.
2.11.9 USING THE 996PSP PIPE SIMULATOR
Using the proper coupling compound, mount the transducers on the pipe simulator as shown on the
next page. Slide each transducer until it presses against a pin-stop. Use the clamping screws to hold
the transducers in place.
¦ Access the Installation Menu. Select [Meter Type] [Single, Dual, or Quad Channel] depending on
meter type. Select the meter channel (1,2,3, or 4) depending on which measurement channel you
intend to test. Select [Clamp-On] and then [Channel Setup].
¦ Access the [Channel/Path Setup] menu. Move the highlight to [Create/Name Site]. Create a new
Site Setup (e.g., TEST1). You can now enter data without altering an existing Site Setup.
