 - 4 -                Figure 7  Insert 2xLR6 (AA size) batteries into the transmitter, the LED located in the back of raincollector will be turned on for 4 seconds, then it will be off and start to work normally. The transmitter will make a data transmission and then start radio controlled time reception routine. If time signal can be detected correctly, the LED will start to flash 5 times, and then the LED will be on for 20s, indicating time signal has been found correctly. When time signal is bad and reception is not possible, the transmitter will terminate radio controlled time reception within one minute and resume normal mode. When there is a data transmission happened, the LED will be on for 20ms. During radio controlled time reception period, there is no transmission and normal transmission will only resume after time reception routine is complete. The longest time for radio controlled time reception is 5 minutes.   Receiver /Indoor unit After inserting the batteries into the Weather Station, all LCD segments will be turned on for a few seconds, all possible display segments are turned on for checking.           After this, the weather station will make initial measurement and start to register the transmitter (the radio reception icon will be turned on). Do not press any key before outdoor sensor data received, otherwise the outdoor sensor learning mode will be terminated. When outdoor transmitter has been registered, the base station will automatically switch to the normal display mode from which all further settings can be performed by the user.       If no RCC signal is detected in the initial setup, the transmitter will try once every two hours to get an RCC signal until a signal is received. Once the transmitter receives the RCC signal it will transmit the signal to the monitor. On the monitor the RCC tower icon will be displayed, if the monitor doesn’t receive the RCC signal or loses the signal continuously for 12 hours the RCC icon will not be display.   Note for RCC signal: The best condition for reception is at night, between midnight and 6:00am – when there is less atmospheric interference.  Note: If a battery change on the transmitter side happened, the receiver will be resynchronized to the transmitter again within the next 3 hours. If you want to shorten the receiving data time, the base station has to re-install the battery so that it can have the new security code learnt right way, but the previous weather data and alarm value settings in receiver will be lost.   Note:  Commonly the radio communication between receiver and transmitter in the open field can reach a
 - 5 - distance of up to 330 feet providing that there are no interfering obstacles such as buildings, trees, vehicles, high voltage lines, etc.       Radio interferences such as PC screens, radios or TV sets can, in bad cases, entirely cut off radio communication. Please take this into consideration when choosing standing or mounting locations.         Mounting Before placing and installing all components of the weather station at there final destination, please set up the weather station with all parts being nearby for testing the correct function. If e.g. there appear to be problems with the 433 MHz radio transmission, they can mostly be overcome by moving the mounting locations.  Transmitter (thermo-hygro sensor), rain collector, wind direction sensor have been mounted onto the mast. You just need to assemble the wind cups attached.     Attaching the Wind Cups 1. Push the wind cups onto the anemometer’s stainless steel shaft. 2. Use the Allen wrench provided to tighten the set screw on the side of the wind cups. 3. Spin the wind cups. If the wind cups spin freely, the anemometer is ready and can be installation.   Figure5                                 Note On the edge of wind direction sensor, there are four alphabet letter of “N”,”E”,”S”and “W” representing for the direction of North, East, South and West. Wind direction sensor has to be adjusted so that the directions on the sensor are matching with your real location. Permanent wind direction error will be introduced when the wind direction sensor is not positioned correctly during installation.  Level the sensors Use the bubble level on the rain sensor as a guide to verify that sensors are level.     Push cups onto stainless steel shaft Tighten screw with Allen wrench

 - 7 - y  Wind Speed Calibration (default is 1.0, adjustment rang 0.75 to 1.25) y  Rainfall data Calibration (default is 1.0, adjustment rang 0.75 to 1.25) y History rainfall Calibration y  Outdoor humidity Calibration   y Outdoor temperature Calibration y Indoor humidity Calibration y Indoor temperature Calibration   Wind Speed Calibration Wind speed is the most sensitive to installation constraints. The weather station should not be located close to buildings, trees or other obstructions.  Many installations are not perfect and installing the weather station on a roof can be difficult. Thus, you can calibrate for this error with a wind speed multiplier.  In addition to the installation challenges, wind cup bearings (moving parts) wear over time.  Without a calibrated source, wind speed can be difficult to measure. We recommend using a calibrated wind meter and a constant speed, high speed fan. Temperature Calibration Temperature errors can occur when a sensor is placed too close to a heat source (such as a building structure, the ground and when placed in direct sunlight without proper shielding in hot weather environments).  To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer. Bi-metal (dial) and other digital thermometers are not a good source and have their own margin of error. Using a local weather station in your area is also a poor source due to changes in location, timing (airport weather stations are only updated once per hour) and possible calibration errors (many official weather stations are not properly installed and calibrated).  Place the sensor in a shaded, controlled environment next to the fluid thermometer, and allow the sensor to stabilize for 48 hours. Compare this temperature to the fluid thermometer and adjust the console to match the fluid thermometer. Humidity Calibration Humidity is a difficult parameter to measure accurately and drifts over time. Humidity errors can occur when placed too close to the ground, near grass or other sources of humidity.  The hygrometer sensor utilizes a capacitor, which varies as a function of humidity. Due to manufacturing tolerances, the accuracy of the sensor is ± 5%. To improve on this accuracy, the indoor and outdoor humidity readings can be adjusted or calibrated from the display console.  To calibrate humidity, you will need an accurate source, such as a sling psychrometer or Humidipaks One Step Calibration kit.  Rainfall calibration   The Rain Collector is calibrated at the factory so the bucket tips (and records rainfall) for each 0.01" (or 0.3 mm) of rain. To calibrate rainfall, we recommend a tube type rain gauge. Use a rain gauge with an aperture of at least 4 inches. Any smaller and the readings obtained may not be accurate. Place the tube type rain gauge directly next to the rain collector. Compare the totals on three storms. Based on this,
 - 8 - develop an average for how far off the readings are.  Do not compare rainfall readings to reading obtained from television, radio, newspapers, or neighbors’ readings. Such readings are not located in your specific environment and therefore are not an accurate measurement of the weather readings taking place in your surroundings. The rain collector is carefully tested at the factory to conform to the specifications listed in the back of this manual.  The history rainfall calibration factor is applied to the running total, not individual tips. All of the rainfall figures are calculated from the total number of tips recorded by the station since it was reset. The total is multiplied by 0.3 to get a total in mm. This is then converted to inches if necessary by multiplying by 0.0393700787. The calibration multiplier is then applied to this, and this is the figure that remembers and compares each time a new total is read from the station.
