Take your and the other Measurements (which, I suppose, are measure on 
another place nearby, where the real amount of rainfall may vary to your 
place more or less) yout measurements are off with ~factor 10.

so you could configure:

[StdCalibrate]

[[Corrections]]

rain = rain / 10


If it is really off by a certain factor, you could do so.

To check that, place a bucket near the rain sensor, then compare your 
measure value to the value your sensor delivers. The amount of mm is the 
amount of water in liters divided by the area of the opening of the bucket 
in square meters. Or the amount of water in kilograms divided by the is the 
area of the opening of the bucket in m².
