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 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.

This instrument is not user serviceable. For technical assistance, contact the

sales organization from which you purchased the product.

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.
