Norcross IR101SP User manual

The Infrared Thermometer SP has an accuracy of
plus or minus 4° F (2.5° C) and is not intended to be
a scientific instrument. Do not use this device if you
require accuracy greater than this tolerance.
To Avoid Personal Injury, Follow These Guidelines:
•Do not point laser directly at the eye or indirectly
off reflective surfaces.
• Do not use the thermometer if it operates abnor-
mally. When in doubt, have the thermometer
serviced by a certified NorCross®repair facility.
• Do not operate the thermometer around explo-
sive liquids, gases, or vapors.
• Reflective objects will often result in lower than
actual temperature measurements. Do not
touch any surface suspected of being hot.
• Do not use in a manner not specified by this manual.
To Avoid Damage to the Thermometer, Follow These Guidelines:
•Do not expose to EMF (electro-magnetic fields) from arc welders, induction
heaters, etc.
• Do not expose to static electricity.
• Do not expose to thermal shock caused by large or abrupt ambient tempera-
ture changes. Allow 30 minutes for the thermometer to stabilize to a new
environment before use.
• Periodically wipe the case with a dry cloth. Do not use abrasives, cleaning
chemical or solvents on this device. If necessary use a damp cloth to remove
debris buildup.
• Do not store in a high temperature environment (automobile, vehicle or boat
dashboard, direct sunlight, etc).
• Remove the batteries during storage to prevent damage from leaking batteries.

How the Thermometer Works
This thermometer is a non-contact infrared thermometer. It measures the sur-
face temperature of a non-translucent object by detecting the infrared energy
emitted by the object. The laser is used for aiming purposes only.
Installing the Batteries
1. Locate the battery compartment on the back of the unit.
2. Use your fingernail to pry the tab down and remove the
battery cover.
3. Install one “A23” 12 Volt alkaline battery (included).
Make certain to align the battery as per the illustration
in the battery compartment.
4. Lubricate the battery cover seal as per the instructions
below.
5. Reinstall the battery cover by installing the bottom first,
then press the tab into place until it “clicks”.
Using the Buttons
1. °C/°F - Press and release to change the units of meas-
ure (Celsius to Fahrenheit). The current setting will
appear as °C or °F in the bottom right corner of the
LCD.
2. LIGHT- Press and release to turn the backlight ON.
The backlight will turn ON for 10 seconds.
3. LASER - Press and release to turn the laser ON or
OFF. When the laser is ON, the icon will be illumi-
nated on the LCD.
4. MEASURE ON - Press and hold to obtain continuously
updated readings. The unit will automatically turn OFF
in 10 seconds after releasing the button.
IMPORTANT:
To ensure the waterproof integrity of your thermometer,
lubricate the rubber seal around the battery door with
Petroleum Jelly (Vaseline®) or Silicon Grease each time
you change the battery.

Warning:
This thermometer is not recommended for use in measuring the tem-
perature of shiny or polished metals. It may be possible to compen-
sate for inaccurate readings that may result from measuring shiny
metal surfaces by covering the surface with tape or flat black paint
and directing the laser at the taped or painted surface.

Measurement Spot Size
Readings are projected in what is known
as a Distance/Spot Ratio (D:S). The D:S
is a measurement of the diameter of the
temperature measurement area as it
relates to the distance between the
device and the surface being read. The
D:S for this thermometer is 5:1
(127:25.4 mm), which means that every
5 inches (127 mm) that the device is
from the target, it measures a 1” (25.4
mm) diameter spot on the target. You
must consider this when using the ther-
mometer.
Operating the Thermometer
Before activating the thermometer, find a target that’s about
twice as large as the thermometer’s spot size. The most
accurate readings are obtained at a distance of 3 to 12 inch-
es (75 to 300 mm) from the target.
• The thermometer turns ON when you press the “Measure
On” button and continuously updates the readings until the
button is released.
• Once the “Measure On” button is released, the device will
hold the last reading for 10 seconds and then turn OFF.
Keep in Mind:
• Always hold the thermometer PERPENDICULAR to the
target measurement surface.
• Shiny or polished surfaces can give inaccurate readings. To measure these
types of surfaces, cover the surface with tape or paint and allow the tape or
paint to adjust to the surface temperature before measuring.
• The unit can not measure through transparent surfaces such as glass or plas-
tic. When trying to measure through these surfaces you will obtain temperature
readings of the glass or plastic surfaces.
• Air particles such as steam, dust, or smoke can interfere with the thermometers
ability to give accurate readings.
• Readings may be affected if the unit is operated within intense RF or electro-
magnetic fields. Discontinue use under these conditions.
Frequently Asked Questions
Can this thermometer measure air temperature?
No and Yes. No, because air’s infrared emissivity is too low to be detected.
However, you can measure air temperature by taking the temperature of any
object that is not affected by external heating sources (sunlight, air vents, lights,
etc).
Can this thermometer measure the temperature of anything?
No and Yes. Gold, aluminum, reflective metals, or any low emissivity material
Measure ON
Measures the temperature of a 1” spot,
every 5 inches that the unit is held from
the measurement object.

will provide inaccurate readings. When trying to measure the temperatures of
these types of items, cover the measurement surface with tape or flat black
paint.
What are some common materials that I can measure the temperature of?
Plastic, glass, ceramics, cloth, skin, water (most liquids), soil, foliage, rubber,
wood, or any non-shiny metal surfaces.
What applications is the temperature meter good for?
• Checking water temperature , proper water circulation, misfiring of spark
plugs, clogged fuel injectors, exhaust temperatures on any engine.
• Checking tire brake and hub temperatures on cars, trucks and trailers.
• Determining water and livewell temperatures while fishing.
• Check the temperature of any household appliance (refrigerator, freezer, Air
Conditioner, Heater, etc). Setting hot water heater thermostats to prevent
accidental scalding.
