2. Do not use the product under conditions that doesn’t match the environmental requirements. For specific use environment requirements, see the product parameter table.

3.Notice to user

3.1 Calibration

Annual calibration to the thermal camera is recommended to ensure the accuracy of temperature measurement, either through IRAY TECHNOLOGY or third-party organizations.

3.2 Accuracy

For accurate measurement, the below operations are recommended.

1. Use the thermal camera after it is stable for 30 minutes.
2. Operation distance is 0.5m~1.5m, and 0.7m~1.2m is the ideal distance.
3. This thermal camera is designed for ultra-temperature measurement, so it’s not recommended to monitor the targets at the normal temperature.

3.3 Usage

In order to avoid the prolonged stress on the connecting parts and improve the product stability, it’s recommended to make proper support for the lens during integration use.
