Page 10: Introduction
TE525 Tipping Bucket Rain Gage Introduction The TE525 Tipping Bucket Rain Gage is an adaptation of the standard National Weather Service tipping bucket rain gage. It outputs a switch closure for each bucket tip. Three models are available: TE525 6 in. orifice 0.01 in. -

(3) Screws from original manufacturer QuickStart Short Cut is an easy way to program your datalogger to measure the TE525 and assign datalogger wiring terminals. Short Cut is available as a download on www.campbellsci.com. It is included in installations of LoggerNet, PC200W, PC400, or RTDAQ. -
Page 12: Overview
Overview TE525-series Tipping Bucket Rain Gages funnel precipitation into a bucket mechanism that tips when filled to a calibrated level. A magnet attached to the tipping mechanism actuates a switch as the bucket tips. The momentary switch closure is counted by the pulse-counting circuitry of Campbell Scientific dataloggers. -
Page 13: Snowfall Adapter
Campbell Scientific’s CS705 Snowfall Conversion Adapter uses antifreeze to melt snow, allowing the TE525WS to measure the water content of snow. The CS705 cannot be used with either the TE525 or TE525MM. However, both the TE525 and TE525MM can be converted to a TE525WS by returning them to Campbell Scientific (see page at the beginning of this document). -

(2.2 lb) (2.4 lb) 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 for the multiplier. -

To create a pulse, an internal 100 kΩ... -

CM270 Installation Do the following to mount the tipping bucket rain gage to the CM270 bracket (FIGURE C-3): NOTE Follow this procedure to ensure that the tipping bucket is mounted correctly. The adjustment screws for the tipping mechanism will not be accessible if it is mounted incorrectly.
- Page 27 Appendix C. CM270 Installation Attach the mounting bracket/tipping bucket assembly to the mounting pipe or mast: Install and level the mounting pipe or mast. Loosen the mounting bracket wingnuts and slide the assembly over the pipe. If necessary, the pole mounting hardware can be removed to get the bolts around the pipe.
- Page 28 The TE525WS rain gage uses a different tipping mechanism that is calibrated differently than the TE525 or TE525MM. The tipping mechanism must be replaced to work with a TE525 or TE525MM funnel. Send the rain bucket into the Campbell Scientific repair department for modifications. Contact Campbell...
