    0.0057 0.1459 The volume of water required to cause a tip in the TE525 and the TE525MM is the same. The difference in calibration is strictly due to funnel size. If the CS705 Snowfall Adapter or other eight inch funnel is installed on these gages, use a multiplier from the last row in TABLE 7-3.

    TE525 Tipping Bucket Rain Gage 7.2.1 Pulse Count Example Programs The following example programs use a pulse channel to read the output from the rain gage. The CR1000 example will also work with the CR800, CR850, CR3000, and CR5000. CR9000(X) programming is similar to the CR1000 except it has an additional parameter in the PulseCount() instruction to specify the pulse module’s slot.
