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

Move the highlight down to [Install Complete?] by triggering the <Down Arrow>. Access the option
list. Move the cursor to [Install] by triggering the <Up or Down Arrow>. Trigger the ENTER sensor 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 triggering the
<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 addi-
tion, 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.
6.9.2 USING THE 996PSP PIPE SIMULATOR
Using the proper coupling compound, mount the transducers on the pipe simulator as shown below.
Slide each transducer until it presses against a pin-stop. Use the clamping screws to hold the transduc-
ers in place.
