RANDOM BUILD
RANDOM BUILD provides assembly continuities (From/To points) for wire ends selected
(touched) at random (no specific sequence is required). A complete procedure is provided
below. Once familiarized, the user may refer to Figure 12.
To select and use RANDOM BUILD in making wire connections, proceed as follows:
1. Load program to be used (refer to "Loading a Program").
2. Attach wrist strap to arm, and plug wrist strap lead into PROBE receptacle on rear panel.
3. Plug foot switch lead into FOOTSWITCH receptacle on rear panel.
4. Connect harness assembly fixture.
5. Press RANDOM BUILD key; the display will show:
Select Next Wire
6. Touch the end of a random wire to assemble, and the display will show the From/To
points.
7. When the correct termination is made, the tone will sound and the display will show:
Select Next Wire
8. Touch each succeeding wire, in any order desired, and make terminations as in Step 5
and 6, above.
9. An "F" will appear at the left of the display when the FROM point is touched, and a "T"
will appear when the TO point is touched. Also, as soon as either the FROM or TO point
is touched, an intermittent tone will sound. The tone and the "F" or "T" will be present
only while the points are being touched.
10. A displayed From/To point may be canceled by pressing either the RANDOM BUILD
key or the foot switch.
11. After all wires are assembled, press TEST to locate any shorts that may have been
created.
NOTE
Only From/To points that are part of the wire list program and
not terminated are displayed. Test points not in the wire list are
not displayed. Refer to the Search mode for displaying points
without using a wire list program.
