2.4.8 THE Ltn VALUE (in)

This view only menu value shows the distance in inches or millimeters between the front
faces of the transducers along the axis of the pipe. If you are mounting the transducers with-
out a track or spacer bar, you will have to space them according to this value (see Section 3 for
details). Note that Ltn may be a negative number for direct mount on very small pipes where
the transducer spacing overlaps.

2.4.9 HOW TO USE [INSTALL COMPLETE?]

Use the [Install Complete?] menu cell to inform the meter that you have mounted the trans-
ducers according to the selected mode and spacing requirements and are ready to start opera-
tion.
To start the [Install Complete?] routine for an original installation:
Select any transit-time mode (e.g., Clamp-On) and press the <Right Arrow>.
Press the <Down Arrow> and scroll to the [Pick/Install Xdcr] menu cell. Press the
<Right Arrow>.

INSTALLATION NOTES

Mount the transducers using the selected mode (direct or reflect). Please refer to the trans-
ducer mounting procedures detailed in Section 3.
When using a mounting track or a spacer bar in reflect mode, locate the first trans-
ducer at the Reference Index and the second transducer at the recommended Number Index.
If you are mounting the transducers independently, you must use the recommended dis-
tance; Ltn to space the transducers.
You must use the proper sonic coupling compound. See "Recommended Sonic Coupling Com-
pounds" in Section 3 for appropriate type and part number.
The pipe must be completely filled with a liquid, which can be either flowing or at zero flow.
Install transducers as required (see Section 3 for procedures).
After transducers are properly mounted, the meter completes its Initial Makeup command
and the [Install Complete?] menu cell appears.
To access the [Install Complete?] option list, press the <Right Arrow>.
Press <Down Arrow> and scroll to the [Install Complete?] menu cell and then press
<ENT>.
Press <ENT>. The [Install Complete?] menu cell will indicate [Yes] after the 1010BX is
successfully installed.
