WARNINGS

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

• Do not direct the 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 the 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 the Emissivity section).

• Avoid using the meter around strong electromagnetic fields.

SAFE PRACTICE

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 as follows:

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

• Maintain this meter properly and calibrate it regularly.

OPERATING INSTRUCTIONS

TEMPERATURE MEASUREMENT

To measure temperature with the IR5E, aim the meter at the object
to be measured, pull the trigger 5 and keep it depressed for at least
two 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 IR5E features dual lasers 8 to assist with targeting the
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 7. Typical diameters of the measurement area as a
function of the distance between the meter and the target area are
depicted below for 12:1 optical systems (Fig. 1).

OPERATING INSTRUCTIONS

BACKLIGHT

The backlight may be toggled on/off by short presses of the Control
button 3. When on, the Backlight icon will be visible on the display.

MODE SELECTIONS

When measuring temperature, the meter continuously samples the
object being measured. Following a measurement, press the Mode
control button repeatedly

1

to cycle through:

• the maximum temperature value measured ('MAX').

• the average value measured ('AVG').

• the difference between the maximum and minimum values
measured ('DIFF').

• the minimum value measured ('MIN').

• Press once more to exit the MODE menu.

SETTINGS

User-adjustable settings may be defined using the SET control button

.

Press SET 2 to enter the settings menu. Subsequent presses of SET
will cycle through the following list of options:

• Emissivity: Set the numerical value of the emissivity to match
the surface being measured (see the EMISSIVITY section
below). When in this setting, the Emissivity icon will flash
onthe display.

• Units: Switch between °F (Fahrenheit) and °C (Celsius). When
in this setting, the '°F' or '°C' icon will flash on the display,
indicating the temperature scale that is currently active.

• Mute temperature limit alarms: (Turn audible limit alarms on/
off) When in this setting, the Audible icon ' ' will flash on the
display. When on, the High 'Hi'/Low 'Lo' icons will be visible.
When off, they will not be visible.

• High temperature limit setting: Assign a numerical value to the
high-temperature limit. When in this setting, the High icon 'Hi'
will flash on the display.

• Low temperature limit setting: Assign a numerical value to the
low-temperature limit. When in this setting, the Low icon 'Lo'
will flash on the display.

When in any setting, control buttons 1 and 3 function as up/
down to adjust settings, and they may be used to select units, turn
alarms on or off, or adjust the numerical values of the respective
parameters up or down.

OPERATING INSTRUCTIONS

EMISSIVITY

Emissivity is a measure of the ability of a surface to emit thermal
energy by radiation. Different types of surfaces (metal, 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 IR5E 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
Grey 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 aluminium 0.09
Cold-rolled steel 0.75 - 0.85

MAINTENANCE

BATTERY REPLACEMENT

When the indicator is displayed on the LCD, the battery must
be replaced.

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

2. Remove the exhausted 9-V battery and dispose of it appropriately.

3. Replace the 9-V battery and then replace the battery compartment
cover, ensuring that it locks into place.

CLEANING

Make sure that the 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 the lens using clean
compressed air. The lens may also be cleaned using a soft
cloth or cotton-wool ball with water or rubbing alcohol

only

.

The lens must be allowed to dry completely prior to use.

STORAGE

Remove the battery when the meter is not in use for a prolonged
period of time. Do not expose to high temperatures or humidity.
After a period of storage in extreme conditions exceeding the
limits mentioned in the General Specifications section, allow the
meter to return to normal operating conditions before using.
