4. Operating Instructions
4.1 Taking a Measurement
To measure the surface temperature of an object:
- Point the pyrometer at the target object.
- Press and hold the TEST button. The dual lasers will activate, indicating the measurement area.
- The temperature reading will be displayed on the LCD screen. Release the TEST button to hold the reading.
4.2 Understanding Distance-to-Spot Ratio (D:S)
The AI-1600APP has a D:S ratio of 30:1. This means that at a distance of 30 units from the target, the measurement spot diameter will be 1 unit. For example, if you are 30 inches away, the measurement spot will be 1 inch in diameter. Maintain an appropriate distance to ensure accurate readings of the desired area.

This image illustrates the dual laser targeting system, which helps users accurately identify the measurement spot, especially important for the 30:1 D:S ratio.
4.3 Adjusting Emissivity
Emissivity (ε) is a measure of an object's ability to emit infrared energy. Different materials have different emissivity values. For accurate measurements, adjust the emissivity setting on the pyrometer to match the target material. The AI-1600APP allows adjustment from 0.1 to 1.0.
- Press the E/Ξ button to enter emissivity adjustment mode.
- Use the UP and DOWN buttons to change the value.
- Press the E/Ξ button again or wait a few seconds to confirm the setting.

This image shows the pyrometer in use across various scenarios, emphasizing the need to adjust emissivity for accurate readings on different surfaces like pizza ovens, grills, and industrial pipes.
4.4 Measurement Modes (MAX/MIN/DIF/AVG)
The device can display maximum, minimum, difference, and average temperature values during a continuous scan.
- While holding the TEST button, press the MODE button to cycle through MAX, MIN, DIF, and AVG display options.
- The selected value will be shown on the display alongside the current temperature.

This image illustrates the pyrometer's display capabilities, showing how it can simultaneously present current, maximum, minimum, and average temperature values.
4.5 Unit Switching (°C/°F)
To switch between Celsius and Fahrenheit temperature units:
- Press the °C/°F button (often labeled T/DN or similar) to toggle between the two units.
4.6 Backlight and Laser Control
To toggle the display backlight or the laser pointers:
- Press the Backlight/UP button to turn the display backlight on or off.
