We suggest that the unit has periodic calibration checks in situ. If the unit is covered by a service agreement with the MOT package installer,

they will carry this out on your behalf. You may however, wish to calibrate the unit yourself.

8. CALIBRATION

The headlamp beam setter can be recalibrated using a laser alignment calibration unit. We recommend the Sealey AK9999 (available from

your authorised Sealey dealer).

We recommend that the laser calibration device be set up and levelled first of all, the beam setter can then be manoeuvred easily on its stand

with reference to the position of the laser. The laser can be placed on any surface such as a car bonnet, box, table etc of suitable height.

8.1 Using the calibrated spirit level within the laser alignment calibration device, ensure that the unit is flat and level.

8.2 Switch the laser on. Manoeuvre the beam setter in order to centre the laser beam in the beam setter lens. This must be done by eye.

There is a ±20mm tolerance on centralisation of the beam through the lens. The beam setter should be approximately 2m from the

laser.

8.3 The dot projected onto the aiming screen should bisect the 0º line, at the far left, centre and far right of the screen. It is necessary at

this point to rotate the column through the vertical axis, to track the beam from one side of the aiming screen to the other. Take care to

ensure that the laser and the beam setter box (see Section 9) remain level throughout.
