rain[e]H3 Precipitation Sensor Manual
5 Introduction
The precipitation sensor rain[e]H3 measures precipitation amount and intensity. The rain[e]H3 combines the
advantages of the latest weighing technology and a self-emptying system, allowing a high resolution and high
precision at a very small total volume. Therefore the rain[e]H3 has a higher resolution and precision than common
tipping bucket sensors and at the same time is much smaller than common weighing sensors, since there is no
need for a collecting container.
The main sensor is a highly precise load cell with overload protection. Its temperature coe󰀩cient can be determined
using a temperature sensor in the interior space if necessary. The pulses from the reed contact generated by tipping
the collecting vessel are used for error correction during periods of high intensity precipitation. Furthermore, the
self-emptying system allows weighing without interruption.
The rain[e]H3 calculates the following values:
►Amount of precipitation
The rain[e]H3 gives the amount of precipitation in real time with a maximum resolution of 0.001 mm.
►Intensity within the last minute
The rain[e]H3 measures 6 times per minute and sums these values up in a moving sum - that is, every
time a new value is measured, it is summed to the previous 5 values and thus generates the new value for
the intensity within the last minute.
►Intensity since last retrieval
The di󰀨erence in the amount of precipitation since the last retrieval is divided by the time since the last
retrieval. If the time is smaller than 30 s, the rain[e]H3 will use the “intensity within the last minute” value.
►Amount since last retrieval
The di󰀨erence in the amount of precipitation between the current and the last retrieval.
►Minimum intensity within the last x minutes (RS485 interface)
Every minute the value of the intensity within the last minute is compared to the current minimum value. If
the new value is smaller, it replaces the former minimum value.
►Maximum intensity within the last x minutes (RS485 interface)
Every minute the value of the intensity within the last minute is compared to the current maximum value. If
the new value is bigger, it replaces the former maximum value.
►Variance
Variance of measured values over 4 s
The RS485 interface can be used in Talker or WL ASCII mode.
6 Heating
The rain[e]H3 is best suited to applications in regions with seasonal or permanent cold climate. The internal heating
is separated in into three parts: A 70 W heater which is installed on the inner side of the funnel, melts sublimate,
a 70 W ring heater heats the funnel opening and a 60 W heating foil under the protection grid and the collecting
funnel prevent complete icing of the outlet. Within its operating temperature of -40…+70 °C the target temperature
of the funnel surface of the heated rain[e]H3 is 2 °C. The operational readiness is checked continuously and can
be requested via the RS485 interface. The heating can be switched o󰀨 via the conguration software rain[e]H3
Commander. In the factory settings the heating is switched on. The heating uses a separate power cable.
Funnel heating and drain heating can be very hot if the heating is operated with the housing open.
There is a risk of being burnt! It is therefore recommended that the connector of the heating
supply be disconnected during cleaning and maintenance work.

7 Installation
7.1 Site Selection
Subsoil conditions
To minimise the entry of splash water it is recommended that sites with hard ground like concrete are avoided.
Place the precipitation sensor on grass or other soft ground instead.
Condition of the surrounding
In general the precipitation sensor should not been placed on slopes or roofs. We recommend installation of the
precipitation sensor at a distance of at least 2 m from any obstacle or the obstacle height (above the gauge’s
orice), as dened by the German Meteorological Service (DWD) or twice the obstacle height as dened by the
WMO and preferably at a distance of four times the obstacle height.
Vegetation around the site should be clipped regularly to the height of the precipitation sensor to prevent them
from disturbing the measurement and at the same time reduce wind inuence.
An additional minimum distance to high-voltage power lines and cell towers is not necessary.
Accuracy of the housing alignment
The housing can be aligned with an integrated spirit level at ±0,7° (blister within the edge of the ring marking). This
accuracy is su󰀩cient for the rain[e]H3. The additional error at 3° inclination is approx. 0.14 %.
7.2 Mounting
Necessary tools
►Wrench (13 mm)
►Allen key (6 mm)
►Slotted screwdriver (approx. 2.5 blade width)
• Unpack the device.
• Take the box of the collecting vessel out of the funnel of the rain[e]H3.
• Check the collecting vessel for transport damage and put it back into its box for later installation.
• Place the sensor on a tube or pole
with an outer diameter of 60 mm. A
metallic extension tube with a mini-
mum length of 100 mm is recommend-
ed if a wooden pole is used. Use a
Wrench (13 mm) to tighten the screws
in the mounting pedestal evenly.
Do not damage the measuring
edge.
• To improve the operating security in
lightning-prone areas it is suggested that
the sensor be earthed via the integrated
earthing screw of the rain[e]H3. The
illustration shows the steps of installation
of an earthing connection with a cable
clip and earthing screws onto the sensor.
The other end of the cable should be
connected to a ground nail.

7.3 Power and Signal Connection
To connect the rain[e]H3 to a data acquisition system a M12 connecting cable is required. Connect the cable
according to the connecting diagram. For the power supply of the heating, a power cable should be connected to
the power supply unit according to the connecting diagram.

It is important to plug in the power plug of the heating rst – before the terminal plug of the funnel
heating and the sensor connector. Otherwise the automatic heating control will shut down the
heating.
The maximum distance between the rain[e]H3 and the data acquisition system depends on the interfaces being
used. The values for RS485 and Ethernet are obtained from the respective denitions of these standards.
• RS485 1000 m
• Ethernet 100 MBit 100 m (CAT-S)
If a power cable longer than 3 m at 0.75 mm2is used for heating supply, this
formula can be used to calculate the actual power Pawith the nominal voltage
UN = 24 V DC, the nominal power PN= 200 W, the specic electrical resistance
ρ =0.017Ωmm²/mforcopper, the length of the cable land the cross section of the
cable A.
The heating requires an actual power Paof higher than 180 W to operate.
The USB cable for the service interface should not be longer than 3 m.
7.4 System Start
The system starts automatically after connecting all plugs. After ~15 s the system starts collecting data and sends
them to the attached data logger according to the device conguration.

8.2.1 Calibration of the Precipitation Value
For the calibration of the rain[e]H3 with the calibration ball as a proxy precipitation, the tab “Scale” is available
in the diagnostic tool of the rain[e] Commander. Select the used COM port (USB Serial Port) and press the gear
button to start the calibration.
Avoid vibrations during the calibration of the rain[e]H3 as this could lengthen the process or in extreme
cases even hinder it!
Follow the instructions of the programme.
For the calibration, the rain[e]H3 must be aligned correctly horizontally!
In the rst step, the rain[e]H3 carries out an empty measurement. The
collecting vessel must therefore be completely empty.
Conrm the query after ensuring that the collecting vessel is empty.!
After the empty measurement, the rain[e]H3 measures the weight of the calibration ball from the calibration set.
Place the ball in the collecting vessel and conrm the query.

rain[e]H3 Precipitation Sensor Manual
The measured weight is indicated by the rain[e]H3. Compare the weight with the weight of the calibration ball
from the calibration set.
The deviation from the test weight should be less than ±0.03 g. Deviations can be caused by external inuences,
e.g. wind.
In the case of signicant deviations, the test should be repeated at least once. For a deviation of >± 0.03 g, the
rain[e]H3 should be adjusted (see “Load Cell Adjustment“).
After calibration, please take the test weight (calibration ball) and put it back in the packaging. Check the correct
position of the blank jacket before putting on the round blank.
8.2.2 Call of Status and Error Messages
The status and error messages can be retrieved by calling the command <STX>USR8<CR><LF> “Get Error
String“ or by using the diagnostic tool of the rain[e]H3 Commander.
Open the tab “Status“ in the diagnostic tool – To check the general operability of the rain[e]H3. Select the COM
port you are using and press the gear wheel button.
As long as the sensor is connected to an external power supply, it can not be reached via the USB interface.
The drain heating can be very hot if the heater is operated with the housing open. There is a risk of
burning!

rain[e]H3 can issue the following errors:
• Overheating error
• Heating error
• Lower temperature sensor (in the interior) error
• Upper temperature sensor (at funnel and ring) error
• Initialisation RTC (real time clock) error
• Outer temperature sensor error
• Power supply error
Overheating error
This error occurs when one of the internal temperature sensors detects a temperature in excess of the congured
“maximum heating temperature”. The factory-provided threshold of the maximum heating temperature is 15 °C.
In this case rain[e]H3 switches automatically OFF until the temperature falls below the error threshold.
Heating error
This error occurs when insu󰀩cient heating capacity is available and the heating current (measured internally)
falls below the threshold of 5.1 A.
Lower temperature sensor error
This error occurs when the lower temperature sensor for heater monitoring stops sending data.
Upper temperature sensor error
This error occurs when the upper temperature sensor for heater monitoring stops sending data.
Initialisation RTC (real time clock) error
This error occurs when the initialisation the RTC (real time clock) fails.
Outer temperature sensor error
This error occurs when the outer temperature sensor for heater monitoring stops sending data.
Power supply error
This error occurs when the quality of the supply voltage varies extremely.
To simulate precipitation amounts, and consequentially to check the output signals at the analogue and impulse
outputs, choose the desired precipitation amount in the rider “simulation” and click “simulate precipitation” (nimbus
symbol). After this, the outputs give the desired amount according to the settings.
