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.
