FIELD CALIBRATION TEST
The Laser Level leaves the factory fully calibrated. Kapro
recommends that the level is checked regularly, and after
the unit has been dropped or mishandled.
Horizontal Line Calibration Test
1. Set up the Laser Level on a flat, vibration-free
surface or tripod as near as possible to a long wall.
2. Unlock the safety lock by setting the switch to ON.
3. Press the Beam Selector button on the keypad to
generate a horizontal beam on the wall.
4. Make two marks through the laser line on the
wall, one very close to the Laser Level and one as far
away as possible.
5. Lock the safety lock, reposition the Laser Level (at the
same height) as near as possible to the far mark on the
wall. Repeat steps 2 and 3.
6. Measure the height difference between the
laser line and the two marks previously made on the wall.
7. If the two measurements are identical, then the
laser level is calibrated.
