Laser Warm Up
Your new laser has been calibrated while it is fully warmed up. In order to ensure proper
calibration, we recommend that you let your laser warm up for at least 30 minutes for
single-plane lasers (L-730 or L-740) and up to 45 minutes for multi-plane lasers (L-732, L-
742, L-733 and L-743).
This does not mean the laser spindles need to be rotating; only that the laser beam should
be turned on for the recommended time.
You can use your laser prior to the warm up time to buck it in (make it parallel) to your
references. However, doing this may result in some laser drift. Accordingly, if you use the
laser prior to the warm-up period, it is recommended that you go back and check your
references before you start taking the alignment measurements. For best results, do not
start taking measurements until the recommended warm time has passed.
It is always a good metrology practice to periodically check your reference points to ensure
the laser or the base (instrument stand, table or other supporting base) it sits upon has not
drifted. Please note that most drift problems are caused by what the laser sits upon, not
due to the laser drifting itself (after the warm up period).
Please call 1-800-826-6185 or +1-203-730-4600 if you have any questions or concerns.
CAUTION!
Surge Protection Strongly Recommended
To ensure the long life of your laser, it is important to plug the A/C adapter into a surge-
protected power source. Despite internal surge protection, a large power surge may cause the
laser diode to burn out, requiring the laser to be returned to the factory for extensive repair.
Failure to plug the A/C adapter into a surge-protected power source may void the warranty.
