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.

5. MEASUREMENT OPERATION
①Hold the meter by its Handle Grip and point it toward the surface to be measured.
②Pull 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.
③While measuring, the SCAN display icon will appear in the upper left hand corner of the LCD.
④While continuing to pull the Trigger:
a. Push the Laser button to turn on the laser pointer. When the laser is on the laser icon will appear on the LCD over the
temperature. Aim the red beam approximately a half inch above the point of test (pressing the Laser button again turns
the laser off).
b. Select the temperature units (oC or oF) using the oCand oFbuttons.
c. Push the Backlight key to turn on the LCD backlighting function.
⑤Release the Trigger and the HOLD display icon will appear on the LCD indicating that the reading is being held.
⑥The meter will automatically power down after approximately 7 seconds after the trigger is released.
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.
6. BATTERY REPLACEMENT
①As battery power is not sufficient, LCD will display “ ” replacement with one new battery type 9V is required.
②Open battery cover, then take out the battery from instrument and replace with a new 9-Volt batter

7. NOTES:
zHow 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.
zField 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.
zDistance & 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.
zLocating 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.

zReminders
- Not recommended for use in measuring shiny or polished metal surfaces ( stainless steel, aluminum, etc.).See Emissivity
- The unit cannot measure through transparent surfaces such as glass. It will measure the surface temperature of the glass instead.
- Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the unit’s optics.
zEmissivity
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.
