It is necessary to obtain a strong bright zone at the
centre of the plate, where the black spot is located.

LUXMETER
13.1.
The Luxmeter (fig.10) is colour graduated for clear reading as follows:
Indicator at BAD/GOOD limit - Use for vehicles travelling under 30mph (40kmh) and
motorbikes.
Indicator at the centre of GOOD - Use for vehicles travelling over 30mph (40kmh).

CALIBRATION
We suggest the unit is periodically checked for calibration in situ. If the unit is
covered by a service agreement with the MOT package installer, they will carry
this out on your behalf. Should you wish to regularly check the calibration yourself,
we recommend you purchase an Alignment Device from your local dealer.
Periodical calibration of the relationship between the test area and the aiming
screen is required. Calibration maybe carried our using an AK9999 Laser
Calibration Gauge or a similar serial numbered laser device calibrated to a
traceable standard. For the purposes of calibration, it is assumed that the vehicle
standing area is flat and level.
14.1.
Place the calibration gauge within the vehicle standing area.
14.2.
Switch on the laser and ensure the beam is flat and level by use of the
integral spirit level.
14.3.
Check that that the optical box is flat and level by checking the spirit
level in the base of the optical box. The spirit level may be viewed
through the plexiglass cover. Adjust the pitch of the optical box by
loosening the screw (See fig.3B). Ensure screw is re-tightened after
adjustment.
14.4.
Project the laser beam through the lens of the optical box. There is a
Ø30mm margin for error in alignment of the beam centrally through the
lens.
14.5.
Align the projected red dot centrally on the screen. The dot should fall
on the hatched 0% line.
14.6.
Move the screen left and right across the beam by rotating the
column and ensure that the dot remains on the 0% line indicating that
the aiming screen is level.
14.7.
If adjustment of the aiming screen is required;
14.7.1.
Undo the four screws which retain the plexiglass cover and remove it.
14.7.2.
Loosen the two screws which retain the aiming screen.
14.7.3.
Adjust aiming screen so that laser dot falls on 0% line.
14.7.4.
Retighten screws and replace cover.
14.8.
Once calibration has been completed the serial numbers of the
beamsetter and the calibration device used to complete
the calibration should be recorded on a suitable document.
This document should be retained for inspection.
