Field Calibration Test - Kapro Prolaser 894 Visi-Cross Manual Del Usuario

FIELD CALIBRATION TEST

The Cross Laser 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 Cross Laser on a flat, vibration-free surface or tripod as near
as possible to a long wall.
2. Turn the lock to ON. Press the H 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. Turn the lock to OFF, 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 calibrated.
Vertical Line Calibration Test
1. Hang a plumb line from a high point on a wall.
2. Set up the Cross Laser on a flat, vibration-free surface or tripod about
3' (1m) from the wall.
3. Turn the lock to ON. Press the V 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.
