Safety Instructions

Warnings

A warning identifies conditions and procedures that are dangerous to the user.
To prevent possible electrical shock, fire, or personal injury follow these guidelines:

• Read all safety information before you use the product.

• Use the product only as specified, or the protection supplied by the product can be

compromised.

• Do not use the product around explosive gas, vapor, or in damp or wet environments.

• Do not use the product if it operates incorrectly.

• See emissivity information for actual temperatures. Reflective objects result in lower than

actual temperature measurements. These objects pose a burn hazard.

• Do not look directly into the laser with optical tools (for example, binoculars, telescopes,
microscopes). Optical tools can focus the laser and be dangerous to the eye.

• Do not look into the laser. Do not point laser directly at persons or animals, or indirectly off
reflective surfaces.

• Use the product only as specified, or hazardous laser radiation exposure can occur.

• Do not use laser viewing glasses as laser protection glasses. Laser viewing glasses are used

only for better visibility of the laser in bright light.

• Do not open the product. The laser beam is dangerous to eyes. Have the product repaired
only through an approved technical site.

• Have an approved technician repair the product.

Cautions

A caution identifies conditions and procedures that can cause damage to the instrument or the
equipment under test.

For safe operation and maintenance of the product:

• Remove the batteries if the product is not used for an extended period of time, or if stored in
temperatures above 50°C (122°F). If the batteries are not removed, battery leakage can damage
the product.

• Recharge the batteries when the low battery indicator appears to prevent incorrect
measurements.

• Have the product repaired before use if the batteries leak.

• Do not short the battery terminals.

• Do not keep cells or batteries in a container where the terminals can be shorted.

• Do not put battery cells and battery packs near heat or fire. Do not put in sunlight.

To avoid damage to the product or the equipment under test, protect them from:

• EMF (electro-magnetic fields) from arc welders, induction heaters, etc.

• Static electricity

3i Plus Rev. A1 Jan 2015 9

Safety Instructions

Battery Warning

The battery is a safety device. Do not attempt to disassemble or alter the battery. Always observe the
following precautions:

• Do not short-circuit the battery by directly connecting the negative terminals with positive
terminal.

• Do not heat the battery or discard it in a fire.

• Do not expose the battery to temperatures over 50°C (122°F). Keep the battery away from fire

and other heat sources.

• Do not charge the battery near a heat source, such as, a fire or heater.

• Do not leave the battery in direct sunlight.

• Do not pierce the battery with a sharp object, hit or step on it.

• Do not use a damaged battery.

• Do not apply solder to a battery.

• Do not connect the battery to an electrical power outlet.

To prevent the battery bursting, igniting, or fumes from the battery causing equipment damage,
always observe the following precautions:

• Do not immerse the battery in water or allow it to get wet.

• Do not place the battery in a microwave oven or pressurized container.

• If the battery leaks or emits an odor, remove it from all possible flammable sources.

• If the battery emits an odor or heat, is deformed or discolored, or in a way appears abnormal

during use, recharging or storage, immediately remove and stop using it.

Instrument

• If the unit is exposed to significant changes in ambient temperature (hot to cold or cold to
hot), allow 30 minutes for temperature stabilization before taking measurements.

• Do not operate the unit near large electrical or magnetic fields such as arc welders and
induction heaters. These fields can cause measurement errors.

• For the short wavelength units (e.g., 1.0 µm and 1.6 µm) — avoid taking temperature
measurements in bright sunlight. High levels of ambient light may produce apparently valid
high-temperature readings when no target is in the thermometer’s field-of-view.

Basics

4 Basics

4.1 Measurement of Infrared Temperature

All objects emit an amount of infrared radiation according to their surface temperature. The intensity
of the infrared radiation changes according to the temperature of the object. Depending on the
material and surface properties, the emitted radiation lies in a wavelength spectrum of approximately
1 to 20 µm. The intensity of the infrared radiation (”heat radiation”) is dependent on the material. For
many substances this material-dependent constant is known. It is referred to as ”emissivity value”
(see section 10.2 Typical Emissivity Values, page 56.
Infrared thermometers are optical-electronic sensors. These sensors are able to detect ”radiation of
heat.” Infrared thermometers are made up of a lens, a spectral filter, a sensor, and an electronic signal­processing unit. The task of the spectral filter is to select the wavelength spectrum of interest. The
sensor converts the infrared radiation into an electrical signal. The signal processing electronics
analyzes the electrical signal and converts it into a temperature measurement. As the intensity of the
emitted infrared radiation is dependent on the material, the required emissivity can be selected on the
sensor.
The biggest advantage of the infrared thermometer is its ability to measure temperature without
touching an object. Consequently, surface temperatures of moving or hard to reach objects can easily
be measured.

4.2 Emissivity of Target Object

Determine the emissivity of the target object as described in section 10.1 Determination of Emissivity,
page 56. If emissivity is low, measured results could be falsified by interfering infrared radiation from
background objects (e.g., heating systems, flames, fireclay bricks, etc., close beside or behind the target
object). This type of problem can occur when measuring reflecting surfaces and very thin materials
such as plastic films and glass.
This measuring error can be reduced to a minimum if particular care is taken during installation, and
the sensing head is shielded from these reflecting radiation sources.

modes and functions, and for full

5 Operation

5.1 Quick Start

To use the instrument right away, complete the following steps:

1. Point the instrument at the object the user wants to measure (as perpendicular as possible to
the object) and pull the trigger. The current temperature (in °C or °F), emissivity value, and
maximum and minimum measured temperature are displayed.

2. Change the emissivity value to correspond to the targeted material by pressing the <F1> key

twice to show the target material table. Press the ▲ and ▼ buttons to select the target material.

For complete definitions of the instrument’s
explanation of operation, refer to the later sections.

5.2 Overview

Portable infrared thermometers measure surface temperatures without touching the surface. They
collect the infrared energy radiated by a target and compute its surface temperature. They also
compute the running average, and maximum/minimum/differential temperatures and present them
on a digital display in either degrees Celsius or Fahrenheit. The instrument is battery-powered or can
be powered by a computer’s USB interface. Internal memory circuits store temperature data for later
recall, and a data-logging feature allows users to store and multiple temperature, emissivity, and
alarm readings (valuable for comparative analysis).

The following figure shows the features of the portable infrared thermometer.

Control Panel and Display: All controls (except the trigger) are located on the control panel. The

display shows temperature and setup values, mode and operating information.

Mini USB Output: Connects the instrument to the PC for downloading data or to DC Adaptor for
charging the battery.

Nose with Temperature Sensor inside: Has the thermistor on the nose for high temperature
protection.

Sighting System: Laser or red dot scope sighting is provided with each model for aiming. Note: Read
the laser warning label before operating the laser.

Polaroid Frame: To adjust brightness of red dot scope.

5.3 Distance and Spot Size

As the distance (D) from the object being measured increases, the spot size (S) of the area measured by
the instrument becomes larger. For the relationship between distance and spot size (D:S), see section

3.2 Optical Charts, page 14.
During measurements, please make sure that the target is larger than the instrument’s measurement
spot size at that distance. The smaller the target, the closer user should be to it.
