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.
