6. FREQUENTLY ASKED QUESTIONS

Question: Level in optical head is not centered during alignment procedure?

Answer:

Level vial is used ONLY when checking the calibration of the floor slope laser.

Question: The high intensity (hot spot) area of the headlamp how is this determine?

Answer:

All lamps are legislated to be created equal, but this has proven not to be the case. The”CVA 3EZ”
ISO

Color incorporates color definition technology that defines the high intensity zone for ease of

alignment. The most inner circle of color is the high intensity zone, this area should be centered over
the area that is designated by the arrow of the specific lamp pattern being aligned.

Question: Do I have to check for floor slope every time I perform a headlamp

alignment?

Answer:

Floor slope need only be performed one time in each bay that the CVA 3EZ is to be used. When
determining the floor slope, record the reading of the rear eccentric wheel on the sticker provided,
Each time you are in that bay, refer to the sticker and adjust the rear eccentric to that measurement.

Question: I cannot attain equal readings at the front wheel and the rear wheel areas when determining the

floor slope.

Answer:

The only time that this can occur is when the shop bay has an abnormally excessive angle of slope.
The most frequent problem with determining floor slope is patience in adjusting until the
measurements are equal. A TRICK to assist in making this measurement is to first measure the height
of the laser at the optical head. Then turn the eccentric wheel until the laser reading matches the
measurement of the optical head at the rear wheel area. Check readings at front and rear wheel areas
and make, if any, minor adjustments to equal measurements. RECORD READING OF ECCENTRIC
WHEEL FOR FUTURE REFERENCE.

Question: What do I use as reference when squaring the CVA 3

to the vehicle and do I need to

square again when moving from one lamp to another?

Answer:

It is always recommended to check the alignment of the line laser to the vehicle for every lamp to be
aligned. Some reference points that are prominent on most vehicles are the grill, hood line, radiator
support, hood bumpers and common assembly point bolts. Always pick two points that are of equal
proportion.

Question: Can the “Visual Assist” meter measure light intensity?

Answer:

The “Visual Assist” meter DOES NOT MEASURE LIGHT INTENSITY. It assists in locating the
highest value reading of that particular lamp. If a light intensity meter is an instrument your facility
would like to procure, SYMTECH offers the “AIM 200”, a hand held, self-contained precision
instrument specifically designed for measuring automotive light intensities.

Question: Why does the “Visual Assist” meter have a higher reading on one side of the car than the other?

Answer:

Most vehicles will have lamps of varying intensity and patterns. Just use the meter and adjust to the
highest value reading for that particular lamp.

Question: Can I use the “Visual Assist” meter to help line up the optical head with the headlamp?

Answer:

YES. While observing the meter, roll the CVA 3

back and forth horizontally and raise and

lower the optical head vertically until you achieve the highest metered reading.

Question: How do I change the batteries in the “Visual Assist” meter?
