Each end of each axis must be checked for calibration. If needed,
the axis can be calibrated, carefully following the instructions. You
can also take the laser to a service center for calibration.
Check and calibrate in this order:
Check both sides of X axis.
• If X is within spec, proceed to check both sides of Y.
• If X needs calibration, calibrate X
Check both sides of Y axis.
• If Y is within spec, proceed to final X to Y check
• If Y needs calibration, calibrate Y; proceed to X to Y check
Final X to Y check: compare X, X’, Y, Y’
Check Z and calibrate if necessary.
4.1 Calibration overview
Calibration is electronic, using the remote control or detector. The
keypad of the laser may also be used, but it will take longer due to
the laser making self-adjustments during movement.
If the beam is visible, calibrate using the non-rotating point. If it’s
too bright to see the beam, you’ll use the detector and will need to
have the beam rotating. When you’re in calibration mode, press
the scan key on the detector to rotate the beam.
The axis LED should blink slowly when in calibration mode. When
the laser is self-leveling or making an adjustment, the LED will blink
rapidly.
IMPORTANT:
When pressing an arrow key to move the beam for
calibration, use short, rapid clicks. Do not hold the key
down. One click will move the beam a very small
amount (1/32" at 150' or 1mm at 100 meters). After
pressing the key, the LED will blink rapidly as the laser
reacts. Wait until the LED returns to a slow blink to
proceed.
3.3 Later recharging
The laser can be charged when working, if electricity is available
on the jobsite. Simply plug in the charger and keep on working.
You can also remove the battery pack to charge it, and replace it
with the alkaline battery compartment to keep on working.
For optimum life of the battery, it is recommended to charge the
battery after fully discharged. To assure battery life, do not charge
over 20 hours.
The battery and the charger can be damaged if damp. Always
store and charge your laser in a dry and covered place.
THIS CHAPTER IS VERY IMPORTANT. Here are a few simple instruc-
tions to check your WLA08 for calibration. Remember that the laser
is a precision instrument and that it is important that you keep it
calibrated and in proper condition.
The accuracy of your job is completely your responsibility and
you should regularly check your instrument especially prior to
important jobs.
The laser has 3 axes: X and Y (horizontal) and Z (vertical), as indi-
cated on the top of the laser.
