Safety Notes
• Unauthorized alteration and/or modification of the Rain Monitor is strictly forbidden due to safety and
approval reasons (CE).
• Only two 1.5V batteries per unit of the product package may be used for power supply.
• Do not expose the Base Station to high temperatures, humidity or severe vibrations as well as
mechanical stress or shock.
• Do not leave any used up batteries in the unit. Even leak proof batteries may corrode and set free
chemicals destroying the batterie compartment or even endangering your health.
• Incorrect polarity of the batteries will without any question immediately ruin the units.
• This product as well as the inserted batteries are not a toy. Keep out of the reach of children.
• Don‘t throw batteries in fire. Danger of explosion!
• This product may not be used for medical purposes or public information.

Product Description
This Rain Monitor serves to measure the amount of rainfall around the home. The funnel in the Rain Gauge
will lead the collected precipitation onto a seesaw formed like a spoon which will then in turn send an impulse
to the Base Station. Transmission of data between Rain Gauge and Base Staion is performed via wireless
433MHz technique.
On the Base Station the amount of rain of the last rainfall, the last hour or the last 24 hours can be polled. An
integrated bar graph shows the amount of rain of the last 7 days, 7 weeks or 7 months respectivelly. All
measured value is stored in EEPROM and will thus not be lost even in case of a battery change. The Base
Station furthermore provides a programmable rain alarm function as well as an integrated 24 hour clock with
date display.
The Base Station is designed for either table standing or wall mounting.
The Rain Gauge will constantly drain itself and is thus safe against any frost damage.

Battery
compartment
With its “RAIN/SET” and “HISTORY/+” keys the Rain Monitor is equipped with only two operating elements
and thus promises a very simple operation. The functions of each key are described in the following:
RAIN/SET Key
When the “RAIN/SET” key is pressed, the following functions will sequentially be displayed in the upper part
of the LCD and will then be repeated:
• TIME
• DATE
• TOTAL rainfall since the Rain Monitor was put into operation
• Amount of rain during the last hour (1H)
• Amount of rain during the last 24 hours (24H)
• Amount of rain since the beginning of the last rainfall (small rain symbol)
HISTORY/+ Key
When the “HISTORY/+” key is pressed, the following bar graph functions will sequentially be displayed in the
lower part of the LCD and will then be repeated:
• DAILY
DAILY shows the rainfall progress in form of vertical bars running from right to left for the past 6 days
and the current day. Every day at midnight (00:00 hours) the bars will shift one place to the left.
• WEEKLY
WEEKLY shows the rainfall progress in form of vertical bars running from right to left for the past 6
weeks and the current week. Every Monday at midnight (00:00 hours) the bars will shift one place to the
left.
• MONTHLY
MONTHLY shows the rainfall progress in form of vertical bars running from right to left for the past 6
months and the current month. On every first day of the month at midnight (00:00 hours) the bars will
shift one place to the left.
Note!
Under normal circumstancec the scaling of the graph bars shows the rainfall up to an amount of 100
millimeters (0, 1, 2, 3, 4, 5, 10, 20, 30, 40, 50 und 100mm). If the rainfall exceeds an amount of 100mm,
the scaling of the entire bar graph will automatically switch to a higher range (0, 10, 20, 30, 40, 50,
100, 200, 300, 400, 500 und 1000mm).
Hanging hole
Numeric Display
If in normal display mode the “HISTORY/+” key is pressed for longer than 2 seconds, the numeric value of
the first bar in the bar graph will be displayed in millimete rs in the top section of the LCD screen. Pressing the
“HISTORY/+” key again will move to the next bar and so on until the values of all bars have been displayed.
Note!
If after display of the value of the last bar of the respective bar graph the “HISTORY/+” key is pressed
one more time or if no key is pressed for 30 seconds then the LCD screen will return to the normal
display mode.
