WARNINGS

To ensure safe operation and service of the meter, follow these
instructions. Failure to observe these warnings can result in
severe injury or death.

• Do not direct laser beam into eyes, as this can cause permanent
eye damage.

• Do not use the meter if the case is damaged in any way.

• Replace the battery as soon as low battery indicator appears.

• Service the meter immediately if it is acting abnormally.

• Be cautious of readings of reflective materials as the meter
may indicate that these surfaces are cooler than their actual
temperature (see Emissivity section).

• Avoid using the meter around strong electromagnetic fields.

SAFE PRACTICES

This meter is designed for professionals who understand the hazards
associated with their trade. While this meter causes no foreseeable
dangers beyond its targeting lasers; the objects being measured,
as well as the environment in which they reside, can be hazardous.
Common safety practices to follow when operating near temperature
critical environments are:

• Follow the manufacturer's maintenance procedures when
servicing equipment.

• Before using this meter to determine if an area is safe, verify
correct operation by measuring a known temperature value of a
comparable object.

• Properly maintain this meter and calibrate it regularly.

OPERATING INSTRUCTIONS

TEMPERATURE MEASUREMENT

To measure temperature with the IR5, aim the meter at the object to
be measured, pull the trigger

and hold it depressed for at least 2

5

seconds. Releasing the trigger initiates Data Hold, "HOLD" will show
on the display, and the measurement will be held on the display.
If the display shows "OL" or "–OL" following a measurement, this
indicates that the surface temperature of the object being measured
is either above or below the measurement range of the meter.

TARGETING

The IR5 features dual lasers

to assist in targeting the

8

measurement area. The distance between the two laser spots on the
surface of the object being measured approximates the diameter
of the circular measurement area from which the infrared sensor is
collecting data. Measurement areas located far away from the meter
will be larger than those close to the meter.

The meter is configured with 12:1 optical resolution (distance-to-spot
ratio). The distance-to-spot ratio defines the size of the measurement
area relative to the distance between the measurement location and
the IR sensor

. Typical diameters of the measurement area as a

7

function of the distance between the meter and the target area are
depicted below for 12:1 optical systems (Fig. 1).

OPERATING INSTRUCTIONS

EMISSIVITY

Emissivity is a measure of the ability of a surface to emit thermal
energy by radiation. Different types of surfaces (metals, masonry,
wood, etc.) emit thermal energy through radiation at different
efficiencies. Accordingly, these materials have different emissivity
coefficients which must be considered in order to make accurate
measurements with an infrared thermometer.

Emissivity on the IR5 may be adjusted from 0.10 to 1.00 to enable
accurate measurement of the temperature of most types of materials.
Generally speaking, shiny bright surfaces such as chrome, white
boards, etc. exhibit lower emissivity than flat black materials.

For guidance only, the chart below may be used to estimate
emissivity for many different types of materials. However, the
emissivity of surfaces is dependent upon many parameters such as
surface finish, temperature, shape of the object, etc.

This chart should be used for guidance only.

Material Emissivity

Asphalt 0.93
Red brick 0.93
Gray brick 0.75
Porcelain ceramic 0.92
Fired clay 0.91
Rough concrete 0.94
Cotton cloth 0.77
Smooth glass 0.92 - 0.94
Granite 0.45
Gravel 0.28
Smooth ice 0.97
Smooth white marble 0.56
Black paint 0.96
Hard rubber 0.94
Wood 0.80 - 0.90
Matte copper 0.22
Commercial sheet aluminum 0.09
Cold rolled steel 0.75 - 0.85

1. Open the battery compartment 6 by pulling the battery
compartment cover at the indentations away from the trigger.

2. Remove exhausted 9V battery and dispose of appropriately.

3. Replace 9V battery and return battery compartment cover,
ensuring that it locks into place.

CLEANING

Be sure meter is turned off and wipe with a clean, dry lint-free
cloth.

Do not use abrasive cleaners or solvents.

Take care
to keep the sensor lens clean at all times. If required, loose
debris may be removed from lens using clean compressed air.
Lens may also be cleaned using a soft cloth or cotton swab
with water or rubbing alcohol

only

. Lens must be allowed to

completely dry prior to use.
