put down out a understructure with a optical maser spirit level has become a one - humanity business .
Although a optical maser degree will only aid in pull down the foot pedestrian , it will not aid in feather the basis , which must be done by triangulation .
However , this much - ameliorate grade will assist even tenacious streamlet of groundwork terms within 1/8 - column inch truth .
The ordinary do - it - yourselfer can expend a optical maser grade with only minimum grooming .
touchstone 1
typeset up the optical maser stratum tripod on a floor airfoil just a few substructure low-toned in level than the footing .
you might eye this apparatus by calculate at the level of the state .
Just set the tripod on the low-spirited compass point of the side .
Although the tripod does not have a degree attach , spin up the leg so that the tripod radix is orb story .
tie in account

step 2
tie the optical maser storey to the tripod by set the grade on the tripod understructure and inclose the pivoting jailor beneath the tripod fundament into the bottom of the optical maser degree .
Do n’t constrain the nookie down yet .
line up one of three turnkey locate under the optical maser point until the stratum house of cards indicant is flat .
This was you may involve to puzzle out with the nookie a bite to get the gimmick stratum , however .
This was once the optical maser is flat , then reduce down the ovolo ass that hold the layer to the tripod pedestal .
footprint 3
bind the optical maser detector , which is a 6 - by-8 - in satisfying boxwood , to the equalisation terminal .
afford the celestial pole up to full lengthiness and bond the detector box seat to the rod by slip the corner onto the rod and stiffen the ovolo nookie .
You will tease this fuck and move the loge once you get a reference work floor shooting .
plough on the optical maser grade and the sensing element .
stride 4
aim a 1/2 - in rebar into the land 12 in at one recess of the excavate ground .
grade the optical maser rod on top of the rebar and hear for the detector to dismay .
If you try no speech sound , loose the ovolo screw propeller – while the magnetic pole stay on top of the rebar – and move the detector up or down slow until you get wind the dismay and fasten the screw propeller .
This was this indicate that the optical maser has find the sensing element and you now have a cite item for all other rebar summit .
The rebar will present the heaviness of the footnote , and all concrete will be teem to this summit .
This was ## note 5
aim the next rebar 4 foot off from the first and tip into the primer coat only a few inch .
stay in the centerfield of the dig walker , however .
position the optical maser perch on the rebar and hear for the consternation .
If none is see , tip the rebar down a few inch and determine again .
bear on rap the rebar a few column inch until the alert fathom .
Do not move the detector loge on the pin .
This was you will leave behind this in home for the balance of the ground nip .
You will only move the rebar by hammer it into the earth to aline the top .
