The bracket can be connected with a standard tripod by 5/8"-11 thread and a 1/4"-20 camera tripod. With the use of the bracket, the laser can be freely rotated, hung on the wall, attached to a metal plate, or bound on staff or pipe with use of its strap. Attach the laser to the bracket using the laser attachment wheel on the bracket.

1624i-English_Manuals 12/28/16 9:27 AM Page 10 8. Calibration IMPORTANT: It is the responsibility of the user to verify the calibration of the instrument before each use. Horizontal Line Transverse Accuracy Check Transverse accuracy refers to the accuracy of the horizontal laser beam projected along the wall, and ensures the beam is level from left to right 1. Set the instrument on a tripod and place approximately 15 ft (5m) from a wall. 2. Unlock the unit and power the unit on. 3.
1624i-English_Manuals 12/28/16 9:27 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 Pitch Accuracy Check Pitch accuracy refers to the accuracy of the laser between the tool and the wall, and ensures that the horizontal beam is level between the tool and the wall. 1. Set up two survey-staffs, OR use two walls, both a minimum of 15 ft (5m) from each other. 2.
1624i-English_Manuals 12/28/16 9:27 AM Page 12 5. Move the tripod as close as possible to wall B, and make the cross dot project on staff/wall A. Make a mark and label as ‘A2’. 6. Rotate the instrument by 180° and move the cross dot to project on staff/wall B. Make a mark and label as ‘B2’. 7. Calculate the vertical distance (A1-A2) – (B1-B2) = e 8. If e> 3/32" at 15 ft, the instrument is out of tolerance and must be calibrated. 12 ©2016 Johnson Level & Tool - Rev.
1624i-English_Manuals 12/28/16 9:27 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 (pitch accuracy). The self-calibration aperture B corresponds with the adjustment of the left/right direction (transverse accuracy). 1. When adjusting, use a 3mm hex tool. 2. The adjustment of both directions will influence each other.
