Normal service condition:
◇The ambient air temperature shall not be higher than +40°C and lower than -5°C , and the average temperature shall not be higher than +35°C within 24 hours.
◇Atmospheric conditions: The air is clean and the relative humidity does not exceed 50% at the maximum temperature of +40°C. Higher relative humidity is allowed at lower temperatures, e.g. 90% at +20°C, but temperature changes should be taken into acc-ount as condensation may occur occasionally.
◇Altitude: not exceeding 2000m.
◇The device is suitable for transport and storage processes at temperatures ranging from -25°C to +55°C and up to +70°C for a short period of time (not exceeding 24h). The device should not suffer any irreversible damage at these limited temperatures and should be able to operate normally under normal conditions.
◇If the above service conditions cannot be met, it shall be settled through negotiation between the user and the manufacturer.
◇When the device is used on offshore oil drilling platform and nuclear power plant, a separate technical agreement shall be signed.
