Input and Vantage Pro Limitations

What we had was a rain gauge input that accepted contact pulses at a rate that the unit thought was acceptable for rainfall. We did not know the limits of the unit in this respect. This information was not available in the basic public information, so we emailed a representative of Davis. He kindly sent me documentation detailing the input/output data of the Vantage Pro. This information gave us insight into the limits of the unit, but still did not answer some basic questions we had such as:

How many pulses (rain) is allowed per month on the display?
What is the conversion factor of pulses to rain?

By experimenting we found that 66 pulses manually applied always produced 0.62 inches of rain. So from this we calculated that 108.64 pulses=1 inch of rain. We also found that 104 inches of rain was the max allowed. That translates to 11,298 pulses. This number is essential to our project because our kWh display relies on the conversion from this rain number. If it reaches the maximum rain, it reaches the max kWh we can record.
