• 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

3i Plus Rev. B3 Aug 2018 17

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 57.
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 57. 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.

Operation

18 Rev. B3 Aug 2018 3i Plus

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 modes and functions, and for full
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.

Operation

3i Plus Rev. B3 Aug 2018 19

Figure 4: Portable Thermometer with Scope

The portable thermometer has the following:

Trigger: One-stage trigger, which activates the unit to take temperature readings.

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.

For accurate measurements the target size must be at least two times bigger than the
Spot diameter

5.4 High Temperature Nose

The instrument has a specially designed nose with high temperature resistant plastic material to avoid
damage from high temperature targets. On the other hand, please avoid over exposure when aiming at
a high-temperature target.
There is a temperature sensor inside the nose. During measurement, the instrument is monitoring the
temperature of the nose. If it is too hot, there will be a warning on the LCD display (ambient highlight
display and backlight change to red plus audible buzzer). Please move the unit away from the high­temperature target when seeing this alarm.

5.5 Power Supply

The instrument is powered by a battery or USB cable when connect to the PC. The battery is located in
the base of the handle.
The instrument provides two charging methods:

• AC adaptor through Mini USB port on the right side of the unit.

• Remove the battery, and use the AC adaptor plus Mini USB-to-DC jack converter to charge. An

indicator on the battery will show a “charging” red light and “charge complete” green light.

The instrument can be powered when connecting the USB cable to the PC but there is
no charging since many USB ports have not enough power capability!

5.6 Display

The display retains the last infrared measurement for 20 s when the trigger is released and <HOLD> is
shown on the display. To hold the infrared temperature, release the trigger until <HOLD> shows on the
display.

Operation

3i Plus Rev. B3 Aug 2018 21

If the measured value is above the upper threshold, the display shows <Hi>. If the measured value is
below the lower threshold, the display shows <Lo>.

5.7 Sighting

5.7.1 Dual Laser

All models use a dual laser method to show the measurement spot position and size. The two laser
points simulate the diameter of the spot circle. The diameter shown by the 2 laser dots is matched quite
well with 90% real spot size at focus distance (4 m (13 ft) away from the unit ), but the laser diameter
becomes greater at a shorter distance. The worst situation is at the lens (0 m (0 ft) away), you can see the
2 laser holes are outside the lens.

5.7.2 Red Dot Scope

The scope models for the Raynger 3i Plus series provide an additional red dot scope; the measurement
target can be seen through the scope. That aiming system can be used when the laser points are hard to
see due to the brightness of the target.
The scope's red dot shows the center of the measuring spot circle, which does not display on the real
object under measurement.
The intensity of the field sight can be adjusted by rotating the knob on the top of the instrument while
keeping the brightness of the red dot. This function is helpful for the user to see clearly the red dot
position when the instrument is measuring high-temperature objects.

If the scope's red dot does not match with the circle of the two laser points, use the following adjustment
method:

1. Open the two circular rubber caps on the top of the unit, and the scope's two adjustable screws

are shown.

2. Affix the unit to a tripod.

3. Aim at a target 4 m (13 ft.) off in the distance, like a wall, for viewing the two lasers clearly.

4. Adjust the two screws on the aiming scope to the center of the two laser points. Please try to

look straight through the aiming scope.

5. Remove the unit from the tripod.

6. Close the two circular rubber caps.

Warning: Please do not use the unit with the two rubber caps open, since unexpected contact with
the screws may introduce noise pulse to the units, resulting in noise readings or disorder of the
display

5.8 Temperature Records

The instrument can store measurement records, including time, date, emissivity, and measurement
record numbers. It can store 1,000 records for basic test data, 10 pcs trend display and 300 records for
profile.
The following types of data are available:

• Basic test data: Test data without a dedicated setting like profile. User can record random

measurement data in this area with a maximum 1,000 records.

• Trend data the data saved under trend mode which includes three screens of data with 360

test values. The data will be saved in a curve format and the user can review the value of each
test point with PC software. Press <View> to review the trend picture. User can press up and

9.2 Lens Cleaning

The user should periodically clean the instrument’s front window.
A dirty front window (lens) can cause temperature measurement errors. The window is fragile, and
care should be taken when cleaning it to prevent scratching. Use camera lens or eye glass tissues to clean
the window.
Periodic cleaning can be done by completing one or more of the following in one of the following ways:

• Blow loose particles off the front window with clean compressed air.

Note: Unfiltered compressed air, as well as user’s own breath, can cause condensation on the

front window, which can trap dust particles instead of removing them.

• Gently brush off particles with a soft camelhair brush.

• Thicker contaminants can be cleaned with water and a camera lens tissue.

• Fingerprints and grease can be removed either with isopropyl alcohol, Ethanol, Xylene,

Acetone, or Kodak® Lens Cleaner. Apply to the front window, and wipe gently with a camera
lens tissue until user see colors on the surface, then allow to air dry. Do not wipe the surface
dry, as this may scratch the surface.

Do not use any ammonia, or cleaners with ammonia, bleach, acids, or strong bases. This
Can cause severe damage to the front window!

9.3 Housing Cleaning

The user should periodically clean the instrument’s housing.
To clean the instrument’s housing, simply use soap and water or a mild commercial cleaner. Wipe with

a damp sponge or soft rag. Use a soft rag to gently wipe the display.

To avoid damaging the instrument, do NOT submerge it in water. Do not use abrasive
Cleaners will damage the case!

9.4 Laser Fault

If the laser (laser models only) does not operate properly, call the supplier of the instrument. DO NOT
open the instrument’s main housing.

10.1 Determination of Emissivity

Emissivity is a measure of an object’s ability to absorb and emit infrared energy. It can have a value

between 0 and 1.0. For example, a mirror has an emissivity of 0.1, while the so-called “Blackbody“
reaches an emissivity value of 1.0. If a higher than actual emissivity value is set, the output will read
low, provided the target temperature is above its ambient temperature. For instance, if the set value is

0.95 and the actual emissivity is 0.9, the temperature reading will be lower than the true temperature.
An object’s emissivity can be determined by one of the following methods:

1. Determine the actual temperature of the material using an RTD (PT100), a thermocouple, or any

other suitable method. Next, measure the object’s temperature and adjust emissivity setting until
the correct temperature value is reached. This is the correct emissivity for the measured material.

2. If possible, apply flat black paint to a portion of the surface of the object. The emissivity of the paint

must be above 0.98. Next, measure the temperature of the painted area using an emissivity setting
of 0.98. Finally, measure the temperature of an adjacent area on the object and adjust the emissivity
until the same temperature is reached. This is the correct emissivity for the measured material.

10.2 Typical Emissivity Values

The following table provides a brief reference guide for determining emissivity and can be used when
one of the above methods is not practical. Emissivity values shown in the table are only approximate,
since several parameters may affect the emissivity of a material. These include the following:

1. Temperature

2. Angle of measurement

3. Geometry (plane, concave, convex)

4. Thickness

5. Surface quality (polished, rough, oxidized, sandblasted)

6. Spectral range of measurement

7. Transmissivity (e.g., thin films, plastics)

Table 8: Typical Emissivity Values

To optimize surface temperature measurements, consider the following guidelines:

• Determine the object emissivity using the instrument, which is also to be used for

measurements.

• Avoid reflections by shielding the object from surrounding temperature sources.

• For higher temperature objects use instruments with the shortest wavelength possible.

• For translucent materials such as plastic foil or glass, ensure that the background is uniform

and lower in temperature than the object.

• Hold instrument perpendicular to surface whenever emissivity is less than 0.9. In all cases, do

not exceed angles more than 30 degrees from incidence.

• For 1M and 2M models, avoid measurements in high ambient light conditions.
