The model MIE0148 infrared thermometer (hereafter, the “thermom-
eter”) can determine the surface temperature by measuring the
amount of infrared energy radiated by the target’s surface.
The thermometers are non-contact infrared thermometer with low
consumption design so that they can be used for a longer time,
which can solve the frequently changing battery and low battery is-
sues during measurement. Intelligent design can make measure-
ment easier and quicker.
INTRODUCTION
SAFETY INFORMATION
Warning
To avoid electrical shock or personal injury, follow these guidelines:
• Do not point laser directly at eye or indirectly off reective sur-
faces.
• Before using the Thermometer inspect the case. Do not use the
Thermometer if it appears damaged. Look for cracks or missing
plastic.
• Replace the battery as soon as the battery indicator appears.
• Do not use the Thermometer if it operates abnormally. Protection
may be impaired. When in doubt, have the Thermometer serviced.
• Do not operate the Thermometer around explosive gas, vapor, or
dust.
• To avoid a burn hazard, remember that highly reective objects
will often result in lower than actual temperature measurements.
• Do not use in a manner not specied by this manual or the pro-
tection supplied by the equipment may be impaired.

Caution
To avoid damaging the thermometer or the equipment under test
protect them from the following:
• EMF (electro-magnetic elds) from arc welders, induction heaters,
etc.
• Static electricity.
• Thermal shock (caused by large or abrupt ambient temperatu-
re changes – all 30 minutes from the Thermometer to stabilize be-
fore use).
• Do not leave the Thermometer on or near objects of high tempe-
rature.
The Thermometer includes:
• Single-spot laser sighting
• White colour backlit display
• Current temperature plus MIN and MAX
• Temperature displays
• Degree celsius and fahrenheit temperature selectable
• Battery power monitoring
• Low battery display

Infrared thermometers measure the surface temperature of an opa-
que object. The Thermometer’s optics sense infrared energy, which
is collected and focused onto a detector. The Thermometer’s elec-
tronics then translate the information into a displayed temperature
reading which appears on the display. The laser is used for aiming
purposes only.
HOW THE THERMOMETER WORKS

EN
The Thermometer turns on when you press the trigger. The Thermo-
meter turns off when no activity is detected for 8 seconds.
To measure temperature, aim the Thermometer at the target, pull
and hold the trigger. Release the trigger to hold a temperature re-
ading.
Be sure to consider distance-to-spot size ratio and led of view. The
laser is used for aiming only.

Locating a hot or cold spot
To nd a hot or cold spot, aim the Thermometer outside the target
area. Then, slowly scan across the area with an up and down mo-
tion until you located the hot or cold spot.

Distance and spot size
As the distance (D) from the target being measured increases, the
spot size (S) of the area measured by the unit becomes larger. The
spot size indicates 90% encircled energy. The maximum D:S is ob-
tained when the Thermometer is 1000mm (100 in) form the target
resulting in a spot size of 20mm (2 in).
Field of view
Make sure that the target is larger than the spot size. The smaller
the target, the closer you should be to it. Suggested distance less
than 75% of the theory value.

Emissivity
Emissivity describes the energy-emitting characteristics of mate-
rials. Most organic materials and painted or oxidized surfaces have
an emissivity of about 0.95.
If possible, to compensate for inaccurate readings that may result
from measuring shinymetal surfaces, cover the surface to be me-
asured with masking tape or at black paint (<1500C / 3020F ) and
use the high emissivity setting. Allow time for the tape or paint to re-
ach the same temperatures as the surface beneath it. Measure the
temperature of the tape or painted surface.
Changing the battery
To install or change the 9V battery, open the battery compartment
the battery.
Cleaning the lens
Blow off loose particles using clean compressed air. Carefully wipe
the surface with a moist cotton swab. The swab may be moistened
with water.
Cleaning the housing
Use soap and water on a damp sponge or soft cloth. To avoid dama-
ge to the Thermometer, do not soak the unit into water.
Caution
To avoid damaging the Thermometer, do NOT submerge it in
water.
