Working with Optional Tripod
A tripod offers a stable, height-adjustable
measuring support. Place the tool via the tripod
mount 3 onto the 1/4"-20 male thread of the
tripod and screw the locking screw of the tripod

Laser Viewing Glasses (Accessory)
The laser viewing glasses 20 filter out the
ambient light. This makes the red light of the
laser appear brighter for the eyes.
• Do not use the laser viewing glasses as
safety goggles. The laser viewing glasses
are used for improved visualization of the
laser beam, but they do not protect against
laser radiation.
• Do not use the laser viewing glasses as
sun glasses or in traffic. The laser
viewing glasses do not afford complete UV
protection and reduce color perception.
