Field Calibration Test - Kapro Prolaser 895 All-Lines Manuel D'utilisation

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 turning the knob on the side of the unit.
Press the Output Control button on the keypad to generate a
horizontal beam on the wall.
3. Make two marks through the laser line on the wall, one very close to
the Laser Level and one as far away as possible.
4. 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.
5. Measure the height difference between the laser line and the two
marks previously made on the wall.
6. If the two measurements are identical, then the laser level is cali brated.
Vertical Line Calibration Test
1. Hang a plumb line from a high point on a wall.
2. Set up the Laser Level on a flat, vibration-free surface or tripod about
3' (1m) from the wall.
3. Unlock the safety lock by turning the knob on the side of the unit.
Press the Output Control button on the keypad to generate a vertical beam.
4. Position the Laser Level so that the vertical laser line touches the base
of the plumb line.
5. If the laser line is also aligned to the top of the plumb line, then the
laser level is calibrated.
