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.

1.0 OVERVIEW
The Model TAC3 is a 32 function tachometer/ratemeter, totalizer/counter, and
timer. It is programmable to read in English or Metric units. An input socket
accepts remote sensing devices and an output socket allows for pulse output
to external indicating devices. The Model TAC3 can be tripod mounted and
“Locked-On” for accurate and continuous operation. This tachometer also
stores minimum, maximum and last measurement in memory.
