DIGITAL INFRARED THERMOMETER 
						

							1
Congratulations on your purchase of the Digital Infrared Thermometer!  Your Digital Infrared
Thermometer is fitted with optical filters that allow you to safely take infrared surface temperature 
readings when contact with the object is not an option.Its convenient laser targeting and high 
distance-to-spot ratio gives you the flexibility to take accurate temperatures of hard to read objects.
SAFETY & WARNINGS
The Digital Infrared Thermometer is a laser device and should be used with caution and care.
Please observe the following guidelines when using this device.
•Infrared thermometers only measure surface temperature.Therefore when used in food applications,
critical temperatures must be verified with an internal temperature-measuring device.
•Do NOT look directly at the infrared beam,or point the beam directly into anyone’s eye(s).
•Do NOT look at the infrared beam from a reflective surface (i.e.,mirror,polished metal,etc).
•Pay attention to your senses.If you feel a burning sensation,turn off the Digital Infrared 
Thermometer immediately.
•Do NOT use near any sources of strong electromagnetic radiation or static electrical charge.
Doing so may cause errors.
•Do NOT direct the laser towards any source of bright or strong light (i.e.,the sun,lamps,etc).
Doing so may damage the sensor.
•If the device experiences significant changes in the ambient temperature,allow at least 20 minutes
for temperature stabilization before taking a new measurement.
•Do NOT allow the lens to come into direct contact with anything.Doing so may scratch or damage
the lens surface which may cause errors.

							OPERATING INSTRUCTIONS
USING THE LASER POINTER FEATURE
Your Digital Infrared Thermometer is equipped with a laser pointer feature that helps you accurately 
target the object you are attempting to measure.While pulling the trigger,press the LASER key 
(FIGURE 1).Repeat to turn the laser pointer feature off.
USING THE BACKLIGHT FEATURE
The back light feature allows you to easily read the LCD display when working in dim conditions.
While pulling to trigger,press the BACKLIGHT key (FIGURE 1).Repeat to turn the backlight off.
SETTING THE TEMPERATURE UNITS
With your Digital Infrared Thermometer,you have the flexibility to switch temperature units between 
˚F or ˚C.While pulling the trigger,press the F/C key (FIGURE 1) until the desired unit is shown on the LCD.
SETTING THE EMISSIVITY 
All surfaces emit thermal radiation.Depending on the temperature,composition and finish of an object,
there is a maximum amount of radiation that any given surface can emit.An object that absorbs all (and
reflects none) of the radiation falling upon it is called a blackbody and has an emissivity value of 1.0.
However,most surfaces are not blackbody emitters and will emit only a fraction of thermal radiation 
that a blackbody would at the same temperature.
FIGURE2 lists the emissivity settings you should use for common objects.Depending on the composition
of the object you are attempting to measure,you may need to adjust the emissivity setting on your
Digital Infrared Thermometer.If you are unsure of which emissivity setting to use,keep in mind that
an emissivity setting of 0.95 will cover 90% of typical applications.

To select emissivity,pull and hold the trigger and press the MODE key.The default emissivity will show
on the LCD.Continue pressing the MODE key (FIGURE 1) until LCD displays desired emissivity setting.

							MAINTENANCE
Your Digital Infrared Thermometer should always be stored in the protective carrying case provided.
This helps keep the lens clean and free of debris which ensure temperature reading accuracy.If the 
lens is soiled,use low pressure compressed air to remove any debris or soil.If the debris cannot be
removed with air,use a soft,slightly damp cotton swab.Only very light pressure should be applied to 
the lens.Do NOT use any solvents or cleaning agents.
CE CERTIFICATION
Your Digital Infrared Thermometer conforms to the following standards:
EN 50081-1/1992 :EN 55022
EN 50082-1/1997 :EN 55024
(EN 6100-4-2/-3/-8,ENV 50204)
The meter complies with the essential protection requirements of Council Directive 89/336/EEC 
on the approximation of the laws of the Member States relating to electromagnetic compatibility.

TAKING A TEMPERATURE READING
1.Hold the device by its handle and pull the trigger.There will be a one second delay,and then the LCD
will come on.
2.While continuing to pull the trigger,point the IR sensor at the object you are attempting to measure
for at least 1 second.Using the laser pointer feature discussed above (confirm location after layout
complete) will help ensure accuracy of the reading.
3.Be sure the measured object fills the “spot”seen by the aperture.
4.Note the temperature on the LCD.
5.The device will automatically retain the last temperature reading on the LCD for 5 seconds after the
trigger is released.
TROUBLESHOOTING
Problem:The Infrared Thermometer display does not turn on.
The time delay feature means the data appears on the display after 1 second – make sure you provide
enough time for this feature.Alternatively,check the battery voltage and replace battery if necessary.
Problem:Dashes appear on the display.
Check the battery voltage and replace battery if necessary.
Problem:Laser comes on,but no data appears on the display.
Measure the surrounding area to your subject to determine if subject exceeds the temperature limit.
BATTERY REPLACEMENT
If the battery voltage falls between 6.5V to 7.5V,a flashing display will indicate that a new battery should
be inserted.While reliable readings can still be obtained within the first few hours of the flashing display,
it is recommended that you replace the battery as soon as possible.
To replace the battery,open the battery compartment (FIGURE 3A).Remove the old battery and install a
new battery (FIGURE 3B).Replace the cover when done.
