Accuracy Self-Check - Plumb point accuracy self-check

1. As shown in figure 1, put the unit on the ground in the direction shown in figure 1-1.

2. Power on the unit and mark the center of plumb-down as point “E” and plumb-up point as “A”.

3. Turn the unit 90° (as shown in figure 1-2) and place the down beam on the “E” mark. Mark the center of the plumb-up point as “B”.

4. Turn the unit 90°again (as shown in figure 1-3) and repeat step 3. Mark the center of the plumb-up point as “C”.

5. Turn the unit 90°again (as shown in figure 1-4) and repeat step 3. Mark the center of the plumb-up point as “D”.

6. Marks A-D should all be in the same spot. If not, the unit will need to be recalibrated. Please see calibration adjustment information.

Accuracy Self-Check - Horizontal Laser (40-6675 only)

1. Set the instrument on a level surface such as a flat head tripod centered between two walls (marked 1 & 2) approximately 25 feet apart. (See fig. 1).

2. Point the instrument directly at wall 1. Turn the laser on and mark the the beam as point A.

3. Turn the instrument 180 degrees so that the laser is pointed directly at wall

2. Turn the laser and mark the beam as point B.

4. Move the instrument and the tripod so the laser is positioned approximately 2 feet away from wall 1 (see fig. 2). Level the tripod and position the instrument on the tripod facing wall 1. Turn the laser on and mark the the beam as point C.

5. Turn the laser off and rotate the laser 180 degrees so that it is facing directly to wall 2.

6. Turn on the laser and mark the beam as point D.

7. Measure the distance between points A & C.

8. Measure the distance between points B & D.

9. If the difference between points A & C and points B & D are less than 1/16”, your instrument is within its tolerance.

10. If it is greater than 1/16”, your unit will need to be recalibrated.
