Open the battery cover. Install the batteries observing correct polarity. Put the battery cover back and push it until a click is heard.
If the symbol of low battery change level appears on the display, replace the batteries by new ones.
Short press the trigger to switch the device on.
The device is ready to work.
The device switches off automatically in 30 seconds after the last press on any button.
Short press the button , to activate the laser point*. Symbol will appear on the display. Short press the button to switch off the laser point. Symbol will disappear from the display. Laser point is only used for aiming and can be switched off when working at short distance to save the battery power.
*Laser point is on as long as the trigger is pressed.
Short press the button to switch on/off the display backlight.
Press and hold the button MODE during 2 seconds to enter parameter setting mode. Symbol Hi will appear on the display. Short press the buttons and to adjust the high temperature alarm limit. To exit the parameter setting mode short press the trigger or press and hold the button MODE during 3 seconds.
Press and hold the button MODE during 2 seconds to enter parameter setting mode. Short press the button MODE to select the setting of low temperature alarm limit (Low). Symbol Low will appear on the display. Short press the buttons and to adjust the low temperature alarm limit. To exit the parameter setting mode short press the trigger or press and hold the button MODE during 3 seconds.
All objects emit thermal energy. The volume of radiated energy depends on the surface temperature and emissivity of the object. The IR-thermometer measures the intensity of radiation and uses it to calculate the temperature of the object. Objects with different surfaces but equal temperature emit different amount of thermal energy. Most of the objects and materials, for example, painted metals, wood, water, leather, fabric have a high emissivity (0.9 and more) and emit more energy than shiny surfaces and unpainted metals with emissivity less than 0.6. Adjustment of emissivity allows the device to take it into account and to minimize the measurement error.

Press and hold the button MODE during 2 seconds to enter parameter setting mode. Press the button MODE 2 times. Symbol will appear on the display. Short press the buttons and to adjust the emissivity value. To exit the parameter setting mode short press the trigger or press and hold the button MODE during 3 seconds.
Press and hold the button MODE during 2 seconds to enter parameter setting mode. Short press the button MODE 3 times. Symbol 0C will appear on the display. Short press the buttons and to select the measuring unit (°C – degrees Celsius / °F – Fahrenheit degree). To exit the parameter setting mode short press the trigger or press and hold the button MODE during 3 seconds.
Switch on the device. Aim the device at the object of measurement and press the trigger. Keep the trigger pressed to enter continuous measurement. Symbol of active measurement will appear on the display. Measurement results will appear on the display in real time mode.
If measurement result is beyond the set limit, LED indicator turns red, the symbol Hi or Low appears on the display. When the trigger is released, the device keeps the last measured values on the display. The symbol appears on the display.
As the distance from the device to the object increases, the size of the measured spot on object surface increases as well. To determine the size of the spot (S) you need to divide the distance from the device to the target (D) by 12.
Laser points serve as the reference to determine the size and position of measured spot.
