1. The ambient air temperature is not higher than +40ºC, not lower than -5ºC, and its average temperature within 24h is not higher than +35ºC;
2. Atmospheric conditions: clean air, relative humidity does not exceed 50% when the maximum temperature is +40ºC, and higher relative humidity is allowed at lower temperatures, such as 90% at +20ºC, but temperature changes should be taken into account, and condensation may occur occasionally;
3. Altitude does not exceed 2000m;
4. This device is suitable for transportation and storage processes at the following temperatures: between -25ºC and +55ºC. In a short period of time (not more than 24h), it can reach +70ºC. The device should not suffer any irreversible damage at these extreme temperatures, and should work normally under the above conditions;
5. If the above conditions of use cannot be met, the user and the manufacturer should negotiate to resolve;
6. When this device is used on offshore oil drilling platforms and nuclear power plants, a separate technical agreement should be signed.
