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.
Calibration Check
It is recommended to occasionally check the calibration of the LT20.
Horizontal calibration check
• Find a room with a minimum 5m (16’) width
• Turn on both horizontal and vertical lines
• Place LT20 near one of the walls (Fig.1.)
• Mark horizontal line on near wall A
• Rotate the LT20 and mark horizontal wall B.
• Move tripod to location near the other wall (Fig 2)
• Align LT20 so that horizontal line is aligned directly on point B
• Rotate the LT20 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 (1/8”), then accuracy is 3mm at 10m (1.8” 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 LT20 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 LT20 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.
