Product model and meaning

Normal operating conditions

The ambient air temperature is not higher than +40C, not lower than -5C, and its average temperature within 24h is not higher than +35C.

Atmospheric conditions: The air is clean, the relative humidity does not exceed 50% at the maximum temperature of +40C, and higher relative humidity is allowed at lower temperatures, such as 90% at +20C. However, it should be taken into account that temperature changes may occasionally produce condensation.

The altitude does not exceed 2000m.

The device is suitable for transport and storage at temperatures ranging from -25C to +55C, up to +70C within a short period of time (not exceeding 24h), at these limit temperatures the device should not suffer any irreparable damage and should be able to operate normally under normal conditions.

If the above conditions of use cannot be met, it shall be resolved by negotiation between the user and the manufacturer. When the device is used on offshore oil drilling platforms and nuclear power plants, a separate technical agreement shall be signed.
