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
