Battery installation

•Unlock the funnel-shaped top on the rain gauge by turning both knobs on the sides in an anti-clockwise direction.

•Remove the funnel-shaped top lifting it off the rain gauge bucket.

•Remove 7 small screws from the battery compartment cover using a small Phillips screwdriver

•Insert 2 “AA” size alkaline batteries (not included), matching the polarities as shown in the battery compartment.

•Replace the battery compartment door and secure the screws.

•Insert the funnel-shaped top into the rain gauge bucket and secure it in place by turning the knobs clockwise.

Mounting

•Make sure that the rain gauge bucket is level – check inside built-in level for bubble center.

•Place the protective screen over the top to protect the rain gauge from the debris.

•Where practical, mount the rain gauge in place with wood screws (not included).

•Make sure that the rain gauge is in open area where precipitation falls directly into the gauge’s bucket, ideally 2-3 feet above the ground.

Placement tips

•The rain gauge should be placed in an open area away from the walls, fences, trees and other coverings which may reduce the amount of rain falling into the bucket. Additionally, trees and rooftops may be sources of pollen and debris.

•To avoid the rain shadow effects, place the rain gauge horizontally, on the distance corresponding to two to four times the height of any nearby obstruction.

•It is important to locate the unit where rain can flow away freely.
