6.4 Emissivity and Distance Adjustment
For accurate temperature readings, adjust the emissivity setting (0.01-1.00) to match the material being inspected. The camera also allows for distance adjustment (0.3-3m) to compensate for measurement distance.
6.5 High and Low Temperature Alarms
Set custom high and low temperature thresholds. The camera will provide real-time visual alerts on the screen when temperatures exceed or fall below these set points, aiding in early detection of anomalies.
