Tipping Spoons Plastic Tie Test the Rain Collector Before installing the rain collector, test the unit. If you are replacing a rain collector you previously installed, make a note of the total rainfall amount displayed. You may want to reenter this amount after you test the rain collector. 1. Open the transmitter shelter on the ISS.

Install the Rain Collector houses, fences -- and as low as possible out of the wind. To install the rain collector on a sheet metal roof, insulate the unit by making a platform out of wood. Mount the base of the rain collector at least 1" (4 cm) away from any steel or iron surface and make sure the reed switch is at least 1" (4 cm) away from any steel or iron objects (e.g., nails).

Adjusting the Rain Collector Extending Cable Runs If the cable length supplied with the rain collector is not long enough for your purposes, you may extend it. The maximum length of cable is 900 feet (274 m). To extend the cable, purchase standard 4-Conductor Extension Cables from Davis and connect them to the existing rain collector cable. Adjusting the Rain Collector The non-metric version of the rain collector is calibrated at the factory so the spoons tip (and records rainfall) for each 0.01".

Maintaining the Rain Collector Maintaining the Rain Collector For greatest accuracy, you should thoroughly clean the rain collector at least once or twice a year. 1. Disconnect the rain collector cable from the sensor interface in the transmitter shelter. 2. Separate the cone from the base. 3. Use a soft damp cloth to clean pollen, dirt, and other debris from the cone, cone screens, and bucket. 4. Use a pipe cleaner to clear the funnel hole in the cone and the drain screens in the base.
