Reassembling The Case Bottom - Fluke 39 Service Manual

2. Rotate the pca into the case top, aligning the holes in the pca over the six bosses.
Make sure that the pca is pressed down over the ribs of the boss in the upper right
corner of the case top.
3. Align the top edge of the input module with the sealing groove on the case top.
While ensuring the input module remains squarely within the side walls of the case
top, press the input module into the groove until it seats snugly against the top edge
of the case top.
4. Ensure the four leads from the input module remain connected to the pca. The black
wire must be dressed so that it wraps counterclockwise into the connector. Both the
black and red wire must be dressed so they bend outward toward the side of the case
and are not between the pca and the plastic cylinders of the input module.

3-14. Reassembling the Case Bottom

1. Align the bottom edge of the input module with the sealing groove on the case
bottom. While ensuring the input module remains squarely within the side walls of
the case bottom, press the case bottom onto the input module until it seats snugly
against the top edge of the case bottom.
If the case bottom gets cocked at an angle to the sides of the input module, the case
top and case bottom will not come together properly. Make sure the case bottom and
case top are firmly pressed together. The gap width on either side of the instrument,
between the case bottom and case top, should be approximately equal.
2. Reinstall the six Phillips screws into the case bottom.
3. Reinstall the batteries and fasten the battery cover in place using the two slotted
screws.
