SAFETY & MAINTENANCE
The installation site of TBQ-2C total radiation meter shall be selected above the sensing element plane without any obstacles, so as to ensure that there are no obstacles with a height of more than 5 ℃ in the sunrise and sunset directions, and the shadow shall fall on the sensing surface compared to the year. The meter shall not be close to light colored buildings or other objects that are easy to reflect sunlight, and shall not be close to artificial radiation sources.
During installation, the plug of the meter shall be placed facing north, leveled first and then fixed.
The connecting cable between TBQ-2C total radiation meter and recorder shall be double-layer shielded conductor with waterproof performance. The cable shall be firmly fixed on the bracket or buried underground for protection.
The continuous working total radiation meter shall be inspected at least once a day, and the inspection content mainly depends on whether the glass cover is clean. In case of frozen snow, frost, dew, etc., try to gently remove these deposits. In addition, the horizontal and desiccant effectiveness should be checked regularly. There is no moisture in the glass cover.
