Calibration LT-850
Your LT-850 Self-Leveling Grade Laser is a sealed unit and is
calibrated to precise accuracies at the factory. However, if a cali-
bration error is present, we recommend you have your unit
calibrated at a certied Futtura Service Center.
Field calibration is possible if great care taken in following these
instructions.
Upright Position Calibration – X and Y axis
1) To Calibrate the X axis, mount the laser on a tripod or a level,
sturdy surface and place approximately 100 feet (30m) away from
a wall. Face the X axis of the unit to the wall.
2) Establish the new calibration point (C), following the instruction
in Calibration Test.
3) Turn the unit off, then turn the unit back on holding the Mode
Button.
4) The display will now read Co.1 or Co.2 and the laser beam
will turn on and the unit will rotate. Press the mode button until
the display reads Co.1. Now the display will alternate between
Co.1 and a calibration value, which can be a positive or negative
number.
5) Move the detector to the new calibration point (C). With the
Plus and Minus Buttons, increase or decrease the calibration
value until the laser beam moves to the new calibration point.
6) Press the mode button until the display shows Co.2. Repeat 4
and 5 for the Y axis.
7) Pressing the Power button once will store the new calibration
values and then put the unit into the Flat Mode.
8) Follow the Calibration Test instructions to verify the unit is now
calibrated.

Plus and Minus Buttons, increase or decrease the calibration
value until the laser beam moves to the new calibration point.
6) Press the mode button until the display shows Co.2. Wait for it
