2. Sikkerhedsoplysninger

For at sikre sikker drift skal du altid overholde følgende forholdsregler:

• Do Not Point Laser at Eyes: The laser is used for targeting. Avoid direct eye exposure to the laser beam.
• Not for Human/Animal Body Temperature: This infrared thermometer measures surface temperature and is not intended for medical use or measuring internal body temperature of humans or animals. Readings will be inaccurate for this purpose.
• Undgå ekstreme miljøer: Udsæt ikke enheden for ekstreme temperaturer, fugtighed eller ætsende miljøer.
• Batterisikkerhed: Ensure correct battery polarity. Remove batteries if the device will not be used for an extended period.
• Rensning: Brug en blød, damp cloth for cleaning. Do not use abrasive cleaners or immerse the device in water.

4. Opsætning

4.1 Batteriinstallation

The thermometer requires two AAA batteries (included). To install:

1. Find batteridækslet på håndtaget.
2. Åbn låget.
3. Isæt to AAA-batterier, og sørg for at polariteten (+/-) vender korrekt.
4. Luk batterirummets dæksel forsvarligt.

5. Betjeningsvejledning

5.1 Tage en måling

1. Ret termometeret mod måloverfladen.
2. Tryk og hold måleudløseren nede. Laserpegeren aktiveres (hvis aktiveret) for at angive måleområdet.
3. The display will show the real-time temperature. The maximum measured value during the scan will also be displayed.
4. Release the trigger to hold the current reading on the display. The device will automatically power off after 30 seconds of inactivity.

Distance-to-Spot Ratio (D:S): This thermometer has a D:S ratio of 12:1. This means that at a distance of 12 inches, the measurement spot diameter is 1 inch. For accurate readings, ensure the target area is larger than the spot size. The further you are from the object, the larger the measurement area.

5.2 Adjustable Emissivity (0.1 - 1.0)

Emissivity is a measure of an object's ability to emit infrared energy. Different materials have different emissivities. Adjusting the emissivity setting allows for more accurate temperature readings for various surfaces.

• Tryk på knappen 'MODE' for at gå ind i justeringstilstand for emissivitet.
• Use the Up/Down buttons to adjust the emissivity value from 0.1 to 1.0.
• Tryk på knappen 'MODE' igen for at bekræfte og afslutte.

5.3 Enhedsskift (°C/°F)

To switch between Celsius and Fahrenheit, press the dedicated unit button (often labeled °C/°F or integrated into the 'MODE' button functionality).

5.4 High/Low Temperature Warning

This feature allows you to set upper and lower temperature thresholds. If the measured temperature exceeds these limits, an alarm will activate.

• Press the 'MODE' button repeatedly until the 'HI' or 'LOW' alarm setting appears.
• Use the Up/Down buttons to set the desired high or low temperature threshold.
• When a measurement exceeds the set 'HI' value, a red light on the display's upper edge will illuminate, and 'HI' will be shown.
• When a measurement falls below the set 'LOW' value, a red light on the display's upper edge will illuminate, and 'LOW' will be shown.

5.5 Laser On/Off

The laser pointer can be toggled on or off. This is useful in situations where the laser might be distracting or if you prefer not to use it.

• Locate the laser button (often labeled with a laser icon).
• Press the button to toggle the laser on or off.

5.6 Automatisk dvalefunktion

To conserve battery life, the thermometer will automatically enter sleep mode after 30 seconds of inactivity. To wake the device, press the measurement trigger or any mode button.

5.7 Advarsel om lavt batteri

When the battery power is low, a low battery indicator will appear on the display. Replace the batteries promptly to ensure continued accurate operation.

6. Vedligeholdelse

6.1 Rengøring

• Clean the lens with a soft, clean cloth or cotton swab. Do not use abrasive materials.
• Rengør enheden casing med annonceamp cloth and mild soap. Do not use harsh chemicals or immerse the device in water.

6.2 Opbevaring

• Opbevar termometeret på et køligt, tørt sted væk fra direkte sollys.
• Fjern batterierne, hvis de opbevares i længere perioder, for at forhindre lækage.
