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, refer to TABLE 7-2 for the multiplier.

See Appendix C, Changing Funnels with a Different Size, before replacing funnels on any TE525 tipping bucket rain gage with

a different size funnel.

7. Installation

If you are programming your datalogger with Short Cut, skip Section 7.1,

Wiring to Datalogger, and Section 7.2, Datalogger Programming. Short Cut

does this work for you. See Section 4, Quickstart, for a Short Cut tutorial.
