5. Instrucțiuni de utilizare
5.1 Măsurare de bază
To take a temperature reading, simply aim the laser pointer at the desired surface and pull the trigger. The temperature will be displayed instantly. Release the trigger to hold the last reading.
5.2 Comutare unități (°C/°F)
Apăsați butonul „°C/°F” pentru a comuta între unitățile de temperatură Celsius și Fahrenheit.
5.3 Laser Pointer & Backlight Control
Use the dedicated buttons to turn the laser pointer and the backlit display on or off for convenience and battery saving.
5.4 Reglarea emisivității
The thermometer features adjustable emissivity from 0.10 to 1.00. This allows for accurate readings on various materials. The default emissivity is 0.95, suitable for most common surfaces. Refer to the table below for common emissivity values.
Figure 4: Emissivity adjustment on the display with examples for various materials.
5.5 Raportul distanță-punct (D:S)
The device has a Distance to Spot Ratio of 12:1. This means that at a distance of 12 inches, the measurement spot diameter is 1 inch. For optimal accuracy, ensure the target spot is within the measurement area.

5.6 Multifunctional Display
The easy-to-read backlit LCD displays various information including:
- Temperatura curentă
- MAX/MIN Temperature (when in respective modes)
- Data Hold indicator
- Indicator baterie descărcată
- Laser On/Off indicator
- Backlight On/Off indicator
- Setarea emisivității

7. Întreținere
To ensure the longevity and accuracy of your BENETECH GM531 Infrared Thermometer:
- Ștergeți dispozitivul cu o lavetă moale șiamp pânză. Nu folosiți produse de curățare abrazive și nu scufundați în apă.
- Store the thermometer in a dry, cool place when not in use.
- Scoateți bateriile dacă dispozitivul nu va fi utilizat pentru o perioadă lungă de timp, pentru a preveni scurgerile.
8. Depanare
Dacă întâmpinați probleme cu termometrul, luați în considerare următoarele:
- Fără afișare: Verificați instalarea bateriilor și asigurați-vă că bateriile nu sunt descărcate. Înlocuiți-le dacă este necesar.
- Citiri inexacte: Verify the emissivity setting matches the material being measured. Ensure the distance to spot ratio is appropriate for the target size. Avoid measuring through steam or dust, which can interfere with accuracy.
- Laserul nu funcționează: Check if the laser pointer function is enabled.
