MONARCH INSTRUMENT ROLS Quick Start Manual

ROLS
Remote Optical Laser Sensor

SAFEGUARDS AND PRECAUTIONS:

Laser hazards

Eye injury from beam - Do not look into the direct or reflected beam; can cause eye injury up to 25 ft (7.5 m) away.

Visual interference (glare) with pilots and drivers - Interferes with vision up to 525 ft (160 m) away. Can be a
distraction up to 1 mile (1.6 km) away. NEVER point any laser towards aircraft or vehicles; it is unsafe and illegal.
Safe use guidance
Class 2 lasers are considered safe for accidental eye exposure. Do not look or stare into beam. Do not aim at aircraft.
This is not a toy. Always supervise children.
Read and follow all instructions in this instruction sheet carefully and retain this sheet for future
reference.
Do not use this instrument in any manner inconsistent with these operating instructions or under any
conditions that exceed the environmental specifications stated.
This instrument is not user serviceable. For technical assistance, contact the sales organization from which you
purchased the product.

DESCRIPTION:

The Remote Optical Laser Sensor has a visible red laser light source and green LED
on-target indicator. The class 2 laser source acts as the aiming device during setup
and can accurately measure speeds from 1-250,000 RPM from a distance of up to 25
feet with a maximum offset angle of 60 degrees from the rotating object. The sensor is
housed in a threaded 303 stainless steel tube and supplied with a 90-degree mounting
bracket, jam nuts and an eight foot shielded cable. ROLS-P comes with a 3.5mm (1/8")
male stereo plug adapter. ROLS-W comes with 4 tinned wires.
