5.3 Instrument accuracy adjustment

If the error is more than 3/16" at 100', it is

necessary to adjust the instrument.

When adjusting the instrument:

1. Remove rubber cover to expose the two

calibration set screws.

2. Using a 1.5mm Allen wrench, loosen the two calibration set screws.

3. Rotate the eyepiece seat to make the crosshair center in the reticle of

instrument on the same level with a known reference point. Then

rotate the eyepiece tube to make the horizontal hair on the reticle of

instrument level by using a known level reference point.

4. Tighten the two set screws and restore rubber cover to its original

position.

5.4 Setting Points in Line with use of transit-level

Points A and B are two points which are on a line. Center and level your

instrument over point A; sight on point B. Bring vertical hair exactly on

point B by means of the tangent screw. A pencil held vertically at B is

useful to show this point. Depress the telescope to set points between A

and B on line.

If the top of a stake cannot be seen, when you come to set point C, sight

with the aid of a plumb bob: first, to find where to drive the stake, and

secondly, to note the point on the top of the stake. If it is necessary to

continue this line beyond point C, center and level your instrument over

point B, sight point C and continue this procedure.
