THANK YOU for purchasing a Rain Collector to use with
your WatchDog Micro or Mini Station This manual will aid
you in placement and mounting of the rain gauge. Read
it thoroughly to insure proper and effective use of the
sensor.

This rain collector measures rainfall in 1/100th inch
increments. The self-emptying, tipping bucket design is
accurate and reliable. The rain collector will be accurate
to ±2% at < 2 in (5 cm) per hour.

The rain gauge includes a 6 foot cable that is connected
into port A on models 1115, 1200, 1225, 1400, 1425,
1450, 1525 or 1650 WatchDog Micro Stations or models
2400, 2425, 2450, or 2475 WatchDog Mini Stations. .
Once the sensor is positioned in a representative “micro­climate”, connect the cable into port A to log rainfall data.

Use SpecWare software to program the WatchDog to log
rainfall. Refer to the SpecWare Instruction Manual for
detailed launch and/or readout instructions.

Positioning Sensor

When choosing a location for your rain collector keep the
following in mind:

• Mount the collector on a 1” to 1¼” mast (pipe) using

the u-bolt. Make sure the collector is level when
positioning the mast mount. Use a bubble leveler to
check that the collector’s base is level.

• The gauge contains a magnet-operated switch which

may not operate correctly if you mount the rain
collector on or near any object which attracts a
magnet.

• Choose a location easily accessible for normal

cleaning and is distant from trees and other sources
of pollen or debris.
