Non-Contact Infrared Thermometers
Operating Manual
INTRODUCTION
Thank you for purchase of the IR Thermometer. This is capable of non-contact (infrared) temperature
measurements at the touch of a button. The built-in laser pointer increases target accuracy while the backlight
LCD and handy push-buttons combine for convenient, ergonomic operation.
The Non-contact Infrared Thermometers can be used to measure the temperature of objects’ surface that is
improper to be measured by traditional (contact) thermometer (such as moving object, the surface with
electricity current or the objects which are uneasy to be touched.)
Proper use and care of this meter will provide years of reliable service.
FEATURES:
 Rapid detection function
 Precise non-contact measurements
 Dual laser sighting
 Unique flat surface, modern housing design
 Automatic Data Hold
 °C/°F switch
 Emissivity Digitally adjustable from 0.10 to 1.0
 MAX temperature displays
 Backlight LCD display
 Automatic selection range and Display Resolution 0.1ºC(0.1ºF)
 Trigger lock
 Set high and low alarms
WIDE RANGE APPLICATION:
Food preparation, Safety and Fire inspectors, Plastic molding, Asphalt, Marine and Screen printing, measure ink and Dryer
temperature, HVAC/R, Diesel and Fleet maintenance.
SAFETY
 Use extreme caution when the laser beam is turned on.
 Do not let the beam enter your eye, another person’s eye or the eye of an animal.
 Be careful no to let the beam on a reflective surface strike your eye.
 Do not allow the laser light beam impinge on any gas which can explode.

Distance & Spot Size
As the distance (D) from the object increases, the spot size (S) of the area measured by the unit becomes larger. The relationship
between distance and spot size for each unit is listed below. The focal point for each unit is 914mm (36”). The spot sizes indicate
90% encircled energy.

Note:
 Field of View: Make sure that the target is larger than the unit’s spot size. The smaller the target, the closer you should be
to it. When accuracy is critical, make sure the target is at least twice as large as the spot size.

MODE Button Function
Press the mode button also allows you to access the set state, Emissivity(EMS), Lock
on/off, HAL on/off, HAL adjustment LOW on/off, LOW adjustment. Each time you press
set you advance through the mode cycle. The diagram shows the sequence of
functions in the mode cycle.
EMS adjustment
The Emissivity (EMS) digitally adjustable from 0.10 to 1.0, LOCK on/off. The lock mode is
particularly useful for continuous monitoring of temperatures. Press the up button or down
button to turn on or off. Press the Measurement Trigger to confirm the lock measurement mode.
The IR Thermometer will continuously display the temperaure until press again the
Measurement Trigger.
In lock mode, press the up button or down button adjustable the Emissivity.HAL (LOW) on/off.
Press the up button or down button to turn on or turn off. Press the Measurement Trigger to
confirm the High (Low) alarm mode. Hal (LOW) adjustment. The high (Low) alarm adjustable
form -50 to 550 °C (-58°F ~ 1022°F)
Switching C/F
Select the temperature units (oC or oF) using the oC/oF switch ( ① )
Max indicate the max record that displays between the pressing and releasing the "ON/OFF" button each
time
MEASUREMENT OPERATION
① Hold the meter by its Handle Grip and point it toward the surface to be measured.
② Pull and hold the Trigger to turn the meter on and begin testing. The display will light if the battery is good. Replace the
battery if the display does not light.
③ Release the Trigger and the HOLD display icon will appear on the LCD indicating that the reading is being held. In HOLD
status, press the UP button to turn on or off the laser. And press the DOWN button to turn on or off the backlight.
④ The meter will automatically power down after approximately 7 seconds after the trigger is released.(Unless the unit is
locked on)
Note: Measurement considerations
Holding the meter by its handle, point the IR Sensor toward the object whose temperature is to be measured. The meter
automatically compensates for temperature deviations from ambient temperature. Keep in mind that it will take up to 30
minutes to adjust to wide ambient temperatures are to be measured followed by high temperature measurements, some time
(several minutes) is required after the low (and before the high) temperature measurements are made.
This is a result of the cooling process, which must take place for the IR sensor.
5. BATTERY REPLACEMENT
① As battery power is not sufficient, LCD will display “ ” replacement with one new battery
type 9V is required.
② Open battery cover, then take out the battery from instrument and replace with a new 9-Volt battery and place the battery
cover back.

6. NOTES:
 How it Works
Infrared thermometers measure the surface temperature of an object. The unit’s optics sense emitted, reflected, and
transmitted energy, which is collected and focused onto a detector. The unit’s electronics translate the information into a
temperature reading, which is display on the unit. In units with a laser, the laser is used for aiming purposes only.
 Field of View
Make sure that the target is larger than the unit’s spot size. The smaller the target, the closer you should be to it. When
accuracy is critical, make sure the target is at least twice as large as the spot size.
 Distance & Spot Size
As the distance (D) from the object increases, the spot size (S) of the area measured by the unit becomes larger.
See: Fig: 1.
 Locating a hot Spot
To find a hot spot aim the thermometer outside the area of interest, then scan across with an up and down motion until you
locate hot spot.
 Reminders
① Not recommended for use in measuring shiny or polished metal surfaces ( stainless steel, aluminum, etc.).See
Emissivity
② The unit cannot measure through transparent surfaces such as glass. It will measure the surface temperature of the
glass instead.
③ Steam, dust, smoke, etc., Can prevent accurate measurement by obstructing the unit’s optics.
 Emissivity
Emissivity is a term used to describe the energy-emitting characteristics of materials.
Most (90% of typical applications) organic materials and painted or oxidized surfaces have an emissivity of 0.95 (pre-set in
the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cove the surface
to be measured with masking tape or flat black paint. Allow time for the tape to reach the same temperature as the material
underneath it. Measure the temperature of the tape or painted surface.
