Operation
Laser radiation present.
Before attempting to operate instrument:
• Read and understand the entire manual
• Follow all safety precautions and warning labels
• Do not stare directly into beam
• Use caution when measuring reflective parts
• Do not stare into reflected beam
The Series LX Laser Extensometers must be installed as described in the
Installation section of this Manual. The unit works by sensing reflections from
retro-reflective tape strips applied to the specimen. Two tiny strips are attached to
the specimen, one at each end of the gauge length. These function as targets and
the laser extensometer, via the scanning laser beam, determines the distance
between selected edges of these targets.
CAUTION
