LX Laser Extensometer Safety 23
Safety
Important The Series LX Laser Extensometers are intended for materials
testing laboratories.
The Series LX Laser Extensometers are Class II laser products and, in normal
usage, are not considered hazardous due to the low power of the scanned laser
beam. However, staring into the beam could cause damage to your eyes and
it is up to you to follow all safety precautions and safety labels.
The National Center for Devices and Radiological Health (CDRH) of the U.S.
Food and Drug Administration has established regulations for laser
manufacturers (FDA 21 CFR 1040.10 and 1040.11). The laser extensometer
complies with applicable sections of these regulations and is classified as a Class
II laser product.
A warning logotype, along with other labels identify the unit as a Class II laser
product. Both the warning logotype and the certification label are located on the
control panel, while the manufacturer's identification label is located on the
housing at the rear of the instrument.
In normal usage the laser extensometer is not considered hazardous due to the
low power of the scanned laser beam. However:
Staring into the beam could damage the operator’s eyes.
Use caution when measuring reflective parts.
It is up to the operator to follow all safety precautions and safety labels.
The laser extensometer has the following built-in safety features which should be
checked periodically for proper operation.
• A laser emission indicator that illuminates when power is applied to the
laser.
• A laser disable switch that shuts down the laser.
• A laser shutdown circuit that monitors the scan speed and automatically
disables the laser when the scan speed drops below the limit.
