CS705 Snowfall Adapter 1. Introduction The CS705 Snowfall Adapter converts a TE525WS Texas Electronics Rain Gage to a rain and snow gage. It consists of an antifreeze reservoir, overflow tube, and catch tube. Snow captured in the catch tube dissolves into the antifreeze raising the overall level. The mixture flows through the overflow tube into the tipping bucket where it is measured. A slot in the top of the overflow tube prevents the tube from developing a siphon.
CS705 Snowfall Adapter 3. Initial Inspection 3.1 • Upon receipt of the CS705, inspect the packaging and contents for damage. File damage claims with the shipping company. • Immediately check package contents against the shipping documentation (see Section 3.1, Ships With). Contact Campbell Scientific about any discrepancies. Ships With The CS705 is shipped with the CM270, CS705 Mounting Kit (pn 20621). Refer to FIGURE 4-1 for information on positioning the various mounting hardware.

CAUTION Insert the CS705 antifreeze reservoir into the rain gage funnel. Wear safety glasses during handling and pouring of antifreeze. 6. Fill the reservoir with PGE antifreeze (pn 10869) until a small amount flows out the overflow tube. The reservoir holds ≈2.5 gallons. 7.
CS705 Snowfall Adapter 11. Fasten the catch tube of the CS705 to the mounting pole using the band clamps and storage mount (see FIGURE 4-1). 12. Connect the hose to the 0.5 inch stub at the base of the funnel (see FIGURE 4-1). 13. Place the pail below the rain gage and place the other end of the hose in it. 5.
CS705 Snowfall Adapter 5.2 Tipping Bucket Compatibility The CS705 is equipped with a specially sized cylinder that allows it to nest within the 8-inch orifice of the TE525WS Texas Electronic Rain Gage. The CS705 cannot be directly used with TE525, TE525MM, CS700, or TB4 rain gages. However, the TE525 and TE525MM gages can be converted to a TE525WS at Campbell Scientific. Refer to the Assistance section at the front of this manual for the steps required to return equipment to Campbell Scientific. 6.
CS705 Snowfall Adapter Gages sited improperly and subjected to high winds will under catch winter precipitation generating erroneous data. An improperly sited gage subjected to high winds can be damaged by the wind. 60 to 90 FIGURE 7-1. Proper gage siting 7.2 Mounting Pole A user-supplied mounting pole or Campbell Scientific CM300-series stainlesssteel mounting pole can be used to mount the CS705 away from the tripod or tower.

The manual is also available at www.campbellsci.com. 8. Maintenance The CS705 requires regular site visits. The number of required visits mainly depends on snowfall. Frequent or heavy snows require more site visits.
