1.0 OVERVIEW

The HHT13 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.
