Field Calibration Check
The field calibration check must be performed securely and accurately to make a correct
diagnosis. Whenever an error is registered, have the tool calibrated by a qualified
repair agent.
WARNING:
Always have the laser head calibrated by a qualified repair agent.
Checking accuracy – Plumb (Fig. E–F)
Checking the plumb calibration of the laser can be most accurately done when there is a
substantial amount of vertical height available, ideally 7.5 m (25'), with one person on the
floor positioning the laser and another person near a ceiling to mark the dot created by the
beam on the ceiling (Fig. E). It is important to conduct a calibration check using a distance
no shorter than the distance of the applications for which the tool will be used.
1. Start by marking a point on the floor.
2. Place the laser so that the down beam is centered on the point marked on the floor.
3. Allow time for the laser to settle to plumb and mark the center of the beam created by
the up beam.
4. Turn the laser 180° as shown (Fig. F), making sure that the down beam is still centered
on the point previously marked on the floor.
5. Allow time for the laser to settle to plumb and mark the center of the dot created by the
up beam.
If the measurement between the two marks is greater than shown below, the laser is no
longer in calibration.

Checking Accuracy - Level (Fig. G–J)
Checking the level calibration of the laser unit requires two parallel walls at least 6 m (20’)
apart. It is important to conduct a calibration check using a distance no shorter than the
distance of the applications for which the tool will be used.
1. Place unit 5–8 cm (2"–3") from first wall, facing the wall (Fig. G).
2. Mark the beam position on the first wall.
3. Turn the unit 180˚, and mark the beam position on the second wall (Fig. H).
4. Place the unit 5–8 cm (2"–3") from the second wall, facing the wall (Fig. I).
