RayTek 3i 2.0 OPERATION

Raynger 3i Series Operator’s Manual 2-1

2.0 OPERATION

This portion of the manual contains the following sections:

•Quick Start—To use your unit right away, follow the brief instructions on basic

operating procedures in this section.

•Principles of Operation—A short introduction to infrared thermometry.

•Your Portable Infrared Thermometer—Describes and illustrates the thermome-

ter’s control panel, display, and features.

•How to Operate—A detailed user guide that describes each of the operating

modes. It includes descriptions of the RUN, RECALL, SETUP, and Data Logger

loops.

•Data Outputs—How to use the analog and digital (RS232) outputs to connect the

thermometer to a printer, chart recorder, or computer.

WARNING—LASER SAFETY

Models with laser sighting produce visible laser radiation that may be

harmful to the human eye. Be aware of the following:

• Avoid direct exposure of human eyes to laser light. Eye damage

can result.

• Use extreme caution when operating.

• Never point the unit at another person.

• Keep out of the reach of children.

• Refer to the FDA laser label on the unit for specific information.

IMPORTANT

1. If the unit is exposed to significant changes in ambient temperature

(hot to cold or cold to hot), allow 45 minutes for temperature stabi-

lization before taking measurements.

2. Do not operate the unit near large electrical or magnetic fields such

as arc welders and induction heaters. These fields can cause mea-

surement errors.

3. For the short wavelength units (e.g., 2 µm and below)—Avoid taking

temperature measurements in bright sunlight. High levels of ambi-

ent light may produce apparently valid high-temperature readings

when no target is in the thermometer’s field-of-view.
