WARNING - This product emits a visible beam of laser
light. Avoid exposure to the laser radiation. The use of
optical viewing aids (binoculars, for example) may
increase the ocular hazard.

CAUTION - The laser beam should not be intentionally
aimed at people or animals.

CAUTION - Use of controls or adjustments or
performance of procedures other than those specified
herein may result in hazardous radiation exposure.

Read and follow all instructions in this manual carefully,
and retain this manual 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.

1.0OVERVIEW

The Pocket Laser Tach 200 is a precision hand-held multifunction
Tachometer, Ratemeter, Totalizer and Timer. It is programmable to display
directly in Revs, Inches, Feet, Yards, Miles, Centimeters and Meters or
function as a stopwatch or interval timer. Input / output sockets allow for
remote sensing and pulse output to external indicating devices. For ease of
use, the instrument can be “Locked-on” for continuous operation.
