Printing from Alignment Lasers has become more and more a necessity as customers require a "paper trail" of all work. What we here at Precision Equipment Rental Inc. have done is come up with an idea that helps solve this problem Basically, what we do is use the Printing Tool program that is given out by Pruftechnik, and add another Freeware program to the computer to create PDF files of completed alignments.

    Setting up the Wild/Leica N3 Level: Open the Wild N3 Level instrument carrying case. Remove the Wild N3 Level from the protective case and carefully thread onto the adaptor or tripod. Position the telescope axis parallel to two leveling screws. Rough-level the instrument by adjusting the leveling screws until the bubble in the circular vial is centered. Adjust the level, with the leveling screws, until the split bubbles are in coincidence. Rotate telescope 180 degrees and re-level by bringing the split bubbles into coincidence, using the tilting screw. Observe total number of graduations moved from first position. Turn tilting screw back one-half of total graduations. Bring split bubble into coincidence, using foot screws parallel to the telescope. Rotate the telescope 90 degrees and correct any error with the third plate leveling screw ONLY. Do NOT use the tilting Screw for this adjustment. The instrument should remain level within 1/4 of bubble separation throughout 360 degrees. Each time the telescope is rotated about its vertical axis it will be necessary to bring the split bubble into coincidence before each reading by using the tilting screw. The level is now set up and ready to use.

    The optical micrometer is used when reading an optical tooling scale. By turning the micrometer knob beside the telescope, the Plano parallel glass plate mounted in front of the objective lens is tilted. The objective is to tilt the parallel plate until the horizontal crosshair of the telescope is positioned between a particular pair of scale divisions. The amount of displacement is read off by observing a linear glass scale through the micrometer reading eyepiece.


    The maximum micrometer reading is 0.500 inch. Each graduation of the micrometer scale represents 0.001 inch, with number markings every 0.010 inch up to 0.500 inch.

    To read a given level value the following steps are taken:



    1. Set up and level instrument.
    2. Adjust the micrometer knob until the scale reading in the micrometer reading eyepiece is set to zero.
    3. Index optical tooling scales on points to be leveled.
    4. Rotate telescope about the vertical axis until one scale is viewed through telescope eyepiece.
    5. Tighten horizontal clamp screw.
    6. Bring split bubble into coincidence with the tilting screw. 


    7. Adjust the horizontal tangent screw until the horizontal crosshair is superimposed over the desired vertical line of graduations.

      NOTE: The scale markings are separated in intervals of 0.100 inch each. When rotating the micrometer knob clockwise, the scale will appear to move downward.


    8. Rotate the micrometer knob on the right side of instrument until the horizontal line of the reticule is positionedexactly between two graduations.


    9. When reading from an index point that is located below the level line-of-sight, the micrometer reading added to the scale reading is the total distance between the index point and the line-of-sight.

    Procedure to "Buck-In" a Theodolite or Transit

    If you need to square a roll on a machine, or transfer a point from the line to an overhead conveyor, an instrument needs to be "bucked in". What this means is to locate the instrument exactly on a line parallel to, say an offset centerline, or to a location between two other known points of reference. Repeatable results require careful and thoughtful actions by the instrument man. Care must be taken to protect the instrument AND the reference points. First, select the point to set up the instrument on a tripod.

    This point should be between two reference points. The tripod should be in good condition, preferably made of wood and the use of a tripod stabilizer is recommended. Set the tripod at a suitable height and be sure to use a torpedo level to level the top of the tripod. It is very important to have the top of the tripod LEVEL. Mount the instrument and locate point A carefully with the vertical reticule, and lock the instrument so it cannot rotate. Plunge the telescope and observe point B.

    Move the instrument to the left or right until point B is in line with the vertical reticule. Plunge the telescope and locate point A. Now unlock the instrument and rotate the instrument until point A is in line with the vertical reticule and lock the instrument. Repeat this procedure until the instrument is "Bucked In", always rotating at point A and moving left or right at point B. A lateral slide is a wise choice to move left or right if available.

    • PEG TEST

    Place two level rods approximately 200 feet apart.
    Setup the instrument at the midpoint of the two rods and read each rod.


    Record the readings and note the exact difference.
    Move the instrument closer to either road and, again, read each rod.


    Record the readings and note the exact difference.
    If the read difference doesn’t match, the instrument needs service.
