7. Using the Product
This bracket was specially designed for more extensive adaptability
of the laser. 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.

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. 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 8 ft (2.5m) from Dot ‘A’ and mark on the wall
as Dot ‘M’.
4. Rotate the instrument 90° and make a mark on the wall 15 ft
(5m) from Dot ‘A’. Label this mark as Dot ‘B’.

8 ft (2.5m)
1624i-English_Manuals 12/28/16 9:27 AM Page 10

©2016 Johnson Level & Tool - Rev. 1 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. Set the instrument on a level tripod as close as possible to
wall A.
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’.
1624i-English_Manuals 12/28/16 9:27 AM Page 11

12 ©2016 Johnson Level & Tool - Rev. 1
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 proj-
ect 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.

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-calibra-
tion 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.
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.
