Warn ng!
Do not po nt laser d rectly at eye or nd rectly off reflect ve surfaces.
2. Precaut ons
•After abrupt ambient temperature changes, allow instrument temperature to stabilize for 30
minutes before using for measurement.
•Avoid operating near strong electromagnetic fields such as arc welders, induction furnaces, etc.
•Do not expose thermometer to excessive ambient temperatures.
•Keep the thermometer clean and avoid getting dust into the detector’s optics.
•Do not use solvents to clean the meter.

5. Measurement Pr nc ple
Infrared thermometers detect infrared energy emitted by objects. The instrument focuses energy
through its lens, changing the temperature of a special material that creates an electrical signal.
A microcomputer processes this signal and displays the output on the panel of the thermometer.
The laser is used only for sighting the instrument and has no other effect on temperature
measurement.
6. Measurement Method
1. To measure the temperature of an object, press the trigger to turn on the unit, and then aim the
unit at the object and press the trigger. As long as you hold the trigger, you can measure
temperature continuously. After releasing the trigger, the LCD will hold the temperature values.
The first display indicates the current value. The second display indicates the calculated (Avg.,
MAX, MIN or MAX-MIN).
2. Use the laser button to activate the laser for aiming at distant objects.
3. Use the backlight button to illuminate the display in low-light conditions.
4. Press the “MODE” button to change the second temperature display. This display can show AVG
(average), MAX (maximum), MIN (minimum) or MAX-MIN (span).
5. Press the °C/°F button to change the unit of measure.
6. To measure the ambient temperature, just press “Tamb” key, and then press the trigger down
and keep, you can get the measurement result from LCD directly. After releasing trigger, LCD will
hold the measurement result.

NOTE: The f rst value nd cates the temperature of an object; the second value nd cates the
amb ent temperature.
7. D stance to Spot Rat o
The thermometer has an optical angle and spot size as shown below.
Object Focus tube Sensor
The target should be larger than the unit’s optical spot size. The distance to spot ratio for this
thermometer is 8:1 (8mm spot at 1meter) as shown below.

8. Em ss v ty
Emissivity is a term used to describe the energy emitting characteristics of a material. The higher
the emissivity value a material has, the more infrared energy it will emit at a particular
temperature. Most organic materials range in emissivity between 0.85 and 0.98. This thermometer
has a fixed (non-adjustable) emissivity of 0.95. Measuring objects with an emissivity of less than
0.95 will result in a lower than actual temperature reading on the display. Be aware of this
characteristic when measuring low emissivity objects (e.g. shiny, reflective metal objects).
9. Chang ng the Battery
When the battery is nearly exhausted, the low battery symbol will appear on the display.
The battery should be replaced soon after this occurs. Pinch the both side of the top of the battery
cover to swing it open as shown:
