Vertical Calibration  
Check  
• Find a door jamb about 2m / 6.5’ high.  
• Mark point A at 2.45m / 8’ from door  
jamb  
Turn on LT56 vertical line and place it  
at point A toward the door jamb.  
• Use the vertical line to mark point B  
under the door jamb, mark point C at  
the top of the door jamb and point D at  
2.45m / 8’ beyond the door jamb.  
• Move the LT56 to point D and align the  
vertical line with points A, B and D.  
• Mark the point where the vertical line is  
on top of the door jamb near point C.  
• If the line is within 1mm / 1/32”, the  
vertical line is in tolerance.

• Move tripod to location near the other wall (fig 2)  
• Align LT56 so that horizontal line is aligned directly on point B  
• Rotate the LT56 and mark the horizontal line above/below on on Point A.  
Call this C.  
• The difference between A and C is the accuracy of 2x the distance between  
the walls

12 hours (30 minute quick charge will provide  
2 hours operation with 2 beams)  
Input: 100-240V AC 190 mA  
Output: 5V DC 800mA  
• Example. Distance between the walls is 5m (16’) and distance between A  
and C is 3mm (1/16”), then accuracy is 1.6 mm at 10m (1/16” at 32 ft).
