Applications
Specifications
General Care, Storage and Safety
General safety rules
a) Check the condition of the tool before use.
b) The user must check the accuracy of the tool after it has been dropped or
subjected to other mechanical stresses.
c) Although the tool is designed for the tough conditions of jobsite use, as with
other measuring instruments it should be treated with care.
Cleaning and drying
1. Blow dust off the windows.
2. Use only a clean, soft cloth for cleaning. If necessary, moisten the cloth
slightly with pure alcohol or a little water.
NOTE Do not use any other liquids as these may damage the plastic
components.
Battery disposal
Some areas have regulations regarding the disposal of batteries. Be sure to
dispose of discharged batteries properly.
Calibration Check
It is recommended to occasionally check the calibration of the LT56.
Horizontal calibration check
• Find a room with a minimum 5m (16’) width
• Turn on both horizontal and vertical lines
• Place LT56 near one of the walls (fig.1.)
• Mark horizontal line on near wall A
• Rotate the LT56 and mark horizontal wall B.
• 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
• 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).
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.
Storage
The temperature limits for storage of your equipment must be observed,
especially in winter / summer.
