Use conditions
① Ambient air temperature is not higher than +40℃, not less than -5 ℃. Within 24 hours the average temperature shall not be higher than +35 ℃. Over time, according to the actual situation to reduce capacity operation.
② Indoor use, the altitude of the place of use shall not exceed 2000m.
③ The relative humidity will be less than 50% when the air around the highest temperature is +40 ℃, in the low temperature allowed relative humidity: +20 ~ C is 90%, due consideration should be given to the effects of temperature changes may happen.
④ When installation of the device and the vertical surface of the tilt is not more than 5 degrees, and the whole set of counters relatively flat (in line with the GBJ232-82 standard).
⑤ The device shall be installed in the place where there is no violent vibration and impact and insufficient to make the electrical components be corroded.
⑥ The users have special requirements, can be resolved through consultation with my company.
