Initial Setup - Laser Reference Pro Shot Alpha Operation Manual

Calibration
Although the Alpha transmitter is calibrated at the factory and is an
exceptionally rugged laser, it is worthwhile to check calibration before you
first use your laser. To ensure the best possible results with your laser,
check calibration periodically, or if has been shipped or handled roughly.
Check your setup
Set the tripod in a location away from vehicular and foot traffic. Choose
the location to provide line of sight coverage to the jobsite. The warning
placard should be displayed on the job, and the operator should have an
operator's certificate card. These are included in the instruction packet. It
is a good jobsite practice to check your setup from time to time. Use
engineered benchmarks to assure that your setup is correct and matches
job specifications. On large sites or where accuracy is critical, verifying
the elevation benchmarks you will be working off should be standard
procedure. If there are no suitable benchmarks on the site, you can set
your own by driving stakes and recording their elevations, or by marking
the laser beam height on stable objects such as telephone poles,
concrete walls, etc. The benchmarks should be 90º apart for greatest
accuracy.
Work as close to the laser as possible
You can work up to 1000 feet (305M) from the Alpha laser utilizing the R9
receiver. As with all lasers and optical instruments, the farther you go, the
more error can add up. Set the laser in a safe place, as close as possible
to your work.
Maintain your equipment
Make sure your tripod and mounting hardware are tight, and that your
grade rods are in good condition. This can prevent errors and perfor-
mance problems.
