A. Setting Up for Calibration of Horizontal Lines, Plumb, and Down Beam

1. Use targets with 1/8” scale to check level. 2. Place target at 60ft away (far field target). If space is limited, place target closer

to the tool. The target needs to be scaled according to the distance from the tool.

3. Place a 2nd target approx. 3ft (1m) away from the tool (near field target). (Fig. A-1)

1st 2nd 60ft 3ft Tool Fig. A-1

4. Use a level platform to set the tool on. (Fig. A-2)

check. (Fig. A-3)

3. Turn on the power with horizontal and two vertical lines on. Carefully disconnect the wire connector from the control board and set the housing aside. (Fig. I-3)

(Fig. I-3)

J. Adjusting Vertical Line (Straightness) Back to Calibration

1. Set core on a level stage. Use 1.5mm Hex screwdriver for adjustment. 2. If the vertical line is toward the right side. (Fig. J-1) Adjust the top screw

“clockwise” (tighten) in order to move the line to the left. Note: turn screw slightly since adjustment is very sensitive.

Fig. J-1 3. If the screw is too tight, you will have to slightly loosen (counter clockwise) the

screw that is on the opposite side.

Fig. I-2

4. Adjust until the line is 1/8” within the target. Repeat the above steps until the remaining vertical lines are within specification.

5. Calibration of square needs to be verified after adjusting vertical line straightness. K. Adjusting Horizontal Line (Level) Back to Calibration

1. Set core on a level stage. Use 1.5mm Hex screwdriver for adjustment. 2. If left side of horizontal line is higher, adjust the center screw clockwise (tighten)

to lower the line and vice versa. If the screw is too tight, you will have to slightly loosen (counter clockwise) the screw on the opposite side. (Fig. K-1) Note: turn screw slightly since adjustment is very sensitive.

Fig. K-1 3. If center portion of the horizontal line is higher in the far field target, slightly loosen the 2 top screws and tighten the 2 bottom screws Fig. K-2.

4. If center portion of the horizontal line is lower in the far field target, slightly loosen the 2 bottom screws and tighten the 2 tops screws Fig. K-3.

L. Adjusting Down Beam Back to Calibration

1. Set core on a level stage. Use a 1.2mm Hex screwdriver for adjustment. 2. Observe the location of down beam. When down beam is at the lower position

(Fig. L-1), rotate tool back to initial position and turn screw in clockwise direction to bring the beam downward (Fig. L-2). Readjust mirror until beam is at center of target. Rotate tool 180 degree and recheck beam position. Make more adjustment until beam is within specification. Note: turn screw slightly since adjustment is very sensitive.

M. Adjusting Plumb Beam Back to Calibration

1. Set core on a level stage. Use 1.5mm Hex screwdriver for adjustment. 2. Plumb adjustment is similar to vertical adjustment. Only make small adjustment

at a time on both vertical lines from opposite ends (ex. V1 and V3 or V2 and V4) (Fig. M-1). Misalignment of the line from two opposite ends will create “double line” (Fig. M-2). Note: turn screw slightly since adjustment is very sensitive.

Fig. M-1 Fig. M-2 N. Adjusting Square Back to Calibration

1. Use 1.5mm Hex screwdriver for adjustment. 2. Vertical line toward the right side angle between LD1 and LD 2 is acute (<

90°) & angle between LD 2 & LD3 is obtuse (>90°). (Fig. N-1)

Fig. N-1

3. Loosen (counter clockwise) LD2 screw and tighten the opposite side of the screw

in order to steer the line back to the left side. (Fig. N-2) Note: turn screw slightly since adjustment is very sensitive.
