SET UP RAIN GAUGE
The rain gauge collects rain and takes readings of rainfall
rate and the total rainfall over a period of time. The sensor
can remotely transmit data to the base station.
The base station and rain gauge should be positioned within
an effective range: about 100 meters (328 feet) in an open
area.
The rain gauge should be mounted horizontally about 1
meter (3 feet) from the ground in an open area away from
trees or other obstructions to allow rain to fall naturally for
an accurate reading.
To set up the Rain Gauge:
1. Remove screws and slide the cover off in an upwards
motion.
2. Insert the batteries (2 x UM-3 / AA), matching the
polarities (+ / -). Press RESET after each battery
change.
3. Remove the fibre tape.
To ensure a level plane:
Put a few drops of water on the cross at the base of the
funnel to check the horizontal level.
1
23
4
Water will pool to the center of the cross when the rain
gauge is level.
If water remains on 1-4, the gauge is not horizontal.

EN
5
If necessary, adjust the level using the screw.
NOTE For best results, ensure the base is horizontal to
allow maximum drainage of any collected rain.
RAINFALL
Today’s rainfall appears on the 1st line of the display and
total rainfall is shown on the 2nd line. Press IN / MM to
toggle between inches and millimeters.
RAINFALL HISTORY
The rainfall history is displayed on the second line of the
LCD display. The main unit can record and store up to nine
days of rainfall.
To display the record for a particular day:
Use HIST / UP to toggle between daily rainfall and rainfall
history over the past nine days. The day of the record will be
displayed with a minus (-) sign. Zero (0) means the record
is for the current day.
To clear the current day’s rainfall:
Press and hold SINCE for two seconds. Note that this will
also clear the total rainfall record.
CAUTION Other sensors using the 433 MHz transmission
frequency may influence the rainfall reading. Please avoid
placing those sensors too close to the unit.
TOTAL RAINFALL
The total rainfall is displayed on the 1st line of the LCD
display.
To display the commencing date of the total rainfall record,
press SINCE. The date will appear on the bottom line of
the display.
To clear the existing commencing date and reset it to start
again, press and hold SINCE. The total rainfall and today
rainfall will be reset to zero and the unit will start again to
collect the rainfall data.
RAINFALL ALARM
The rain alarm value can be displayed at any time by
pressing RAIN ALM.
To set the rainfall alarm:
1. Press and hold RAIN ALM for two seconds.
2. Use HIST / UP or DOWN to set the desired value.
3. Press RAIN ALM to confirm. The alarm will be
activated.

EN
6
The rain alarm indicator will light up.
The alarm will go off for one minute when the rainfall reaches
the preset value and the rain alarm indicator will flash. A
reminder beep will be emitted every minute. Once the rain
alarm is on the indicator will not stop flashing unless RAIN
ALM is pressed or the rain alarm value is changed. To stop
the alarm and reminder beep, press any button or change
the rainfall alarm value.
To toggle the alarm ON / OFF, press RAIN ALM ON / OFF.
SIGNALS
