Prepare the Rain Collector
Prepare the Rain Collector
1. Turn the rain collector upside down and remove the cone from the base by rotating the base until the latches on the cone line up with the latch openings in the base then lifting the base away from the cone.
2. Carefully cut and remove the plastic tie which holds the bucket in place during shipping.
3. Insert the optional metric measurement adapter if needed. (See instructions below.)
Insert the Optional Metric Measurement Adapter
Note: The metric version, product number 7852M, comes factory calibrated to take measurements in 0.2 mm.
There is no need to install the metric measurement adapter.
If you have purchased a US version, the rain collector tipping bucket mechanism contains
a standard measurement weight magnet that takes measurements in 0.01” for every tip of
the bucket. If you would prefer readings in metric units rather than inches, you can configure your console to convert the readings to mm’s. (On the console, press either RAIN
key. Press and release 2ND, then press UNITS once.)
However, for the greatest accuracy, you may also install the included metric adapter so
that the rain collector will take measurements in 0.2 mm for each tip of the bucket.
1. Locate the standard measurement weight magnet between the arms of the tipping mechanism.
2. Open the arms slightly with one hand while pulling the magnet out with the other hand.
