get equal light around it. (Picture#4)

6. Attach mini prism pole on top of your xed

the U-joint. Place the prism pole point into the hole

on the bottom plate and tighten the mini prism pole.

Your rod is now plumb- using the three screws under

the bubble just adjust it to level.

Note: By leaving the mini prism pole collet

slightly loose you can rotate your rod. It should

stay level and if not your rod is bent or the True

Plumb is not 100% calibrated. You can also test

regular prism poles with the TPL2000. You do not

need to use the mini prism pole to check calibra-

tion with the regular prism pole.
