5. Safety instructions Damage caused by non-observance of this operating manual can lead to forfeiture of the warranty! We shall not assume any liability for subsequent damage! We shall not assume any liability for damage to items or persons caused by improper handling or non-observance of the safety instructions! In such cases, any guarantee claims shall become null and void .
7. Preparation for operation, commissioning Please observe: First of all, put all available outdoor sensors into operation (insert batteries) and then the base station itself. If you proceed in the opposite order, it could occur that the base station does not detect all the existing outdoor sensors.
Once you have found a favourable location, insert the earth peg deep into the ground in order to ensure the stability of the combination sensor. When selecting the installation site, take the safety of children, pets, vehicles, etc into consideration. Any risk of the combination sensor’s falling poses the risk of injury or danger of damaging vehicles or other objects. You can also use a hammer to insert the earth peg into the ground.

9. Configuration and Operation After installation of the radio sensors and the subsequent commissioning of the base station (this order must be observed!), the data transmitted by the radio sensors should appear on the LC display of the base station.
Calling up configuration mode IN >2 seconds Press key „IN“ for approx. 2 seconds. You can leave the configuration mode at any time by pressing „EXIT“ (= „SENSOR“), see „Terminating configuration mode“. + NEXT - coun + NEXT + NEXT + NEXT + NEXT + NEXT + NEXT - year - month - day - minutes - hours - dst Country selection Set country using the keys „+“ and „-“. • „US“ = USA • „STD“ = Europe Press „NEXT“ key. Setting time and date Set current year using the keys „+“ and „-“.
+ - latitude NEXT + Set the latitude using the keys „+“ and „-“. Example: 52.5°, input: 525 Press the „NEXT“ key. After that, you can enter the longitude. The display shows this as „LO“ („Longitude“). - longitude NEXT Set the longitude using the keys „+“ and „-“. Example: 13.4°, input: 0134 Press the key „NEXT“ and now set the time zone. The display shows „ti”. Setting the time zone The time zone is required for the calculation of the sunrise and sunset times.
Entering the alignment value The rain gauge has been set to a high degree of accuracy ex works so that you normally do not need to align it. Simply press „NEXT“ to take over the factory settings. Otherwise the alignment value will have to be determined first of all in normal mode (see chapter 13 d) on page 27). + - alignment value NEXT Enter the previously determined alignment value using the keys „+“ and „-“. Press „NEXT“ to set the unit for measuring rain.
Selecting the unit for wind velocity The following units can be set: km/h = kilometre per hour m/s = metre per second mph = miles per hour The display will take place in the field „WIND”. + - EXIT wind velocity unit Select the unit with which you wish to display the wind velocity using the keys „+” and „-”. F If the „NEXT“ key is pressed, the country collection will appear again; the input order can commence from the beginning again. You could now, for example, monitor or alter the entries.
• display for the last 24 hours • display for the current 24 hours • display of the total quantity since the last clearance of the rain quantity after inserting the batteries. In the process please consider the following peculiarities: The calculation of the rain quantity „last hour“ always occurs at the half-hour, for example between 2.30 p.m. and 3.30 p.m. The calculation of the rain quantity „last day“ always occurs at 7.30 a.m.
• The desired value can now be displayed by pressing the „SENSOR” several times. Order of display: indoor temperature ‡ indoor humidity ‡ outdoor temperature ‡ outdoor humidity ‡ rain quantity (only MAX value, not for „TOTAL“) ‡ wind velocity (only MAX value) F Only one display field is displayed with its extreme value at one time; the point of time and date of incidence of the extreme value appears below in the time display.
Weather forecast The symbols of the weather forecast from the weather station right at the top of the display give the following forecasts: Overcast with rain ‡ rainy ‡ cloudy Overcast Overcast with sun ‡ bright Sun ‡ sunny Wind symbol display (windsock) The windsock symbol in the display field „WIND” shows at a glance whether the wind is at present light, moderate or strong: Windsock hanging ‡ light wind (< 10 km/h) Airsack half raised ‡ moderate wind (10...
• • • • • Always replace the whole set of batteries. Do not mix full with „half-full” batteries“. Always use four batteries of the same type and manufacturer. Do not mix batteries with accumulators. As already mentioned, accumulator operation is possible, the durability is, however, appreciably lower than with batteries. • For changing the batteries, proceed as described in section 7. c). F Please observe the following: After replacing the batteries, all data, values stored in the base station (e.g.
11. Troubleshooting Observe the safety instructions contained in these operating instructions Problem Remedy No reception • • • • The distance between the base station and outdoor sensors is too great. Alter the position of the outdoor sensors. Objects or shielding materials are obstructing the radio reception. Alter the position of the outdoor sensors and the base station. The batteries of the outdoor sensors are too weak or flat.
12. Range The transmission range of the radio signals to the base station is 100 m under optimum conditions. This is often described as the „free field range”. F This ideal arrangement (e.g. base station and outdoor sensor on a smooth, level field without trees, houses etc.) is, however, never found in practice. Normally, the base station is set up in the house, the combination in the garden and further outdoor sensors, for example in ancillary buildings or garage.
13. Maintenance and cleaning a) General Check the technical safety of the product regularly, e.g. damage to the housing.
Depending on the location, leaves, particles of dirt carried by the wind, small twigs and similar can enter the cone collector of the rain gauge. Large parts can clog the flow-through! Sand can also collect in the count rocker which will affect the measuring result negatively as it increases. F For this reason, the rain gauge should be cleaned at least once a year. Proceed as follows: • open the lower part of the rain gauge. To do this, turn the lower part approx.
• Insert the rainfall sensor into its holder. It will hold the count rocker firmly automatically. F Only one orientation is correct; the cable of the rainfall sensor and the magnet of the count rocker have to be on the same side; the plastic nib on the other side has to be inserted precisely into the holder, look at the circle in the picture on the right. • Place the cone collector from the top onto the sensor carrier and snap it in by turning it to the left.
d) Aligning rain sensor F The measuring system of the rain gauge has already been set ex works to a high level of exactitude. Any alignment is therefore normally not necessary. The alignment process takes fairly long (at least 10 minutes) and has to be carried out very exactly and conscientiously as, otherwise, the exactitude is much lower than that which already exists. Proceed as follows for alignment: • First of all, set any rain quantity value which may have accumulated back to zero.
14. Handling Observe all the safety precautions in these operating instructions! a) General The product may not be opened or taken apart (except for the work described in these operating instructions, e.g. change of battery or cleaning the rain gauge). There are no parts to be maintained by the user in the inside of the product. The product will be damaged even if dropped from a low height.
15. Terminology Sensed temperature See „windchill“.
The „windchill“ is defined as a cooling down effect on the naked skin with a theoretical surface temperature of 33°C and a wind velocity of over 2.6 m/s. The higher the wind velocity is and the lower the actual environment temperature, the more the windchill effect can be felt.
