The 52202 is shipped with a mounting pipe. The rain gage clamps onto this pipe, which is then fastened to a crossarm using the CM220 Right-Angle Mounting Kit, or mounted onto the top of a tripod using the CM216 Sensor Mounting Kit.
Campbell Scientific offers the 260-953 Wind Screen to help minimize the affect of wind on the rain measurements. This wind screen consists of 32 leaves that hang freely and swing as the wind moves past them.

These rain gages can be connected to either.
Follow the steps listed in the “Troubleshooting” section of the 52202-L Instruction Manual.
If data is not being logged correctly, there are two likely causes:
Not registering any tips, missing tips, or double tips.
Not enough tips or too many tips.
The most common errors are either that the rain gage appears to have drifted out of calibration or that the tips are not being correctly recorded by the data logger.
When a rain gage is out of calibration, it is usually because of the buildup of dirt and grime on the internal surfaces of the tipping bucket mechanism. Cleaning the internal surfaces usually brings the rain gage back into calibration. It is also possible that a rain gage is out of calibration because it is no longer level.
To minimize the possible occurrence of calibration errors, perform routine cleaning and maintenance of the rain gage at least once every three months. The environmental conditions at a particular site may require a facility to perform cleaning, leveling, and maintenance on a much more frequent schedule.
The 260-953 Alter-type rain gage wind screen consists of 32 heavy metal leaves that hang freely and swing as the wind moves past them. The swinging leaves act as a wind damper and help minimize the effect of wind on the rain measurements without adding additional turbulence.
