Laser
level repair & calibration
checklist
used by New England Laser service technicians.
For
Self-Leveling Construction Lasers
• Instrument & all accessories are checked into
our database
the day they arrive.
• Test
all electronic functions
Check control panel for proper function, test voltage from
source to termination, check for liquid damage to PCB & other
power sources.
• Test diode power output
The unit is checked for proper output using our laser diode
power meter.
• Test
for X to Y axis offset error
We test both X axis & Y axis
using our calibration range to determine that each axis coincides
with one another.
•
Test for cone & or wedge error
Using the calibration range
we take a short & long shot reading to determine that both
measurements fall within specification.
•
Test vial block assembly repeatability
We make sure that the calibration
holds its specifications when
the instrument
is taken to all leveling extremes.
•
Test X & Y axis drive motors for binding
By operating the instrument on our automated tilt
table we can determine if the units self-leveling
motors
are binding.
•
Penta prism & optical train are thoroughly
cleaned
By cleaning the laser diode collimator & penta
prism we are assured of maximum power output.
•
Unit is fully calibrated
The unit is placed on our automated
calibration
range & put
through a full calibration sequence.
•
Unit, accessories & case are cleaned
All accessories,
laser & case
are fully cleaned & checked.
For
Compensated Construction Lasers
•
Test all electronic functions
•
Test diode power output
•
Test for X to Y axis offset error
•
Test for cone and or wedge error
•
Test leveling vial to compensator collimation
We
test the compensator & leveling vial & calibrate so
that the two coincide with
one another
•
Test compensator for repeatability
•
Test compensator for sticking
We
set the instrument on calibration range & take
unit to all leveling
extremes to test for
extreme error.
•
Penta prism & optical train are thoroughly cleaned
•
Unit, accessories & case are cleaned
