5. Bedryfsinstruksies
5.1 Basiese Meting
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 Eenheidskakeling (°C/°F)
Press the '°C/°F' button to switch between Celsius and Fahrenheit temperature units.
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 Emissiwiteitsaanpassing
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 Afstand-tot-punt-verhouding (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.
