Conditions Affecting the Laser
Transmitter
The laser transmitter is the grade control reference for the job, and
conditions that can affect the transmitter, also affect the grade, or
quality of work. Once finish grade control reference points are in
place (see “Setting Grade Reference Points” on page 3-14),
continue to verify these points throughout the leveling process.
Succeeding day setups or conditions throughout the day (such as,
laser transmitter drift, atmospheric conditions, wind, and other
factors) can affect the accuracy of grade being cut or filled.
Understanding and identifying these situations will help locate and
fix the problem, allowing you to continue grading.
