8. Self-Check & Fine Calibration

IMPORTANT: It is the responsibility of the user to verify the

calibration of the instrument before each use.

Horizontal Line Accuracy Self-Check (Transversely)

1. Set the instrument on a tripod and place approximately 5 Meters from a wall.

2. Unlock the unit and power the unit on.

3. Face the cross-line laser line to the wall, and set the center as Dot ‘A’. Make a mark on the wall for Dot ‘A’. Make another mark on the wall 2.5 Meters from Dot ‘A’ and mark on the wall as Dot ‘M’.

4. Rotate the instrument 90° and make a mark on the wall 5 Meters from Dot ‘A’. Label this mark as Dot ‘B’.

7048H_Manuals 6/19/13 10:53 AM Page 11

5. Measure the distance ‘e’ from Dot ‘M’ to the laser line, as per the Figure.

6. If ‘e’ > 1.5mm, the instrument is out of tolerance and must be calibrated.

Horizontal Accuracy Self-Check (Longitudinal)

1. Set up two survey-staffs, OR use two walls, both 5 Meters from each other (or further).

2. Set the instrument on a level tripod, and center between the two survey staffs/walls.

3. Power on all laser lines, and move the laser until the cross dot projects on staff/wall A. Make a mark and label as ‘A1’.

4. Rotate the instrument 180° and make the cross dot project on staff/wall B. Make a mark and label as ‘B1’.

7048H_Manuals 6/19/13 10:53 AM Page 12

5. Move the tripod so that the distance between the instrument and staff/wall A is 0.6 Meters, and make the cross dot project on staff/wall A. Make a mark and label as ‘A2’.

Less than 0.6 meters

6. Rotate the instrument by 180° and move the cross dot to project on staff/wall B. Make a mark and label as ‘B2’.

Less than 0.6 meters

7. Calculate (A1-A2) – (B1-B2) = e

8. If e> 1.5mm, the instrument is out of tolerance and must be calibrated.

7048H_Manuals 6/19/13 10:53 AM Page 13

Self-Calibration Adjustment

See the following figure. There are two self-calibration apertures on the instrument. The self-calibration aperture A corresponds with the adjustment of the fore/aft direction. The self-calibration aperture B corresponds with the adjustment of the left/right direction.

1. When adjusting, use a 3mm hex tool.

2. The adjustment of both directions will influence each other. When making fine adjustments in the left/right direction, it might influence the front/back axis. Be sure to repeat the adjustment of both axis when making adjustments to ensure both are accurate.

3. When making adjustment with the adjusting screw, you should not exceed four complete turns of the screw(s).

4. If the unit is still not able to be calibrated, it may be outside of its adjustment range and should be sent to the nearest service center.
