4. Installation of tripod support 4.1. Place The installation place of KWS-2000 must be the representative area of the region for the meteorological observation to obtain more accurate data, and it must be flat surface without huge barriers nearby. If there is high barrier, it is recommended to distance more than 10 times of the height of the barrier (H). The installation place must be avoided to any adjacent of air conditioner/coolant, plant causing high heating, power plant and any damp area after rainfall. If the installation area is an inhabitant or movement route of animals or insects, the protection and maintenance must be considered too. Caution There must be no adjacent high-tension line nearby tripod support installation place. When installing fixed post or earth bar underground, check high pressure gas, and waste pipe before the work. 4.2 Tools for installation and assembly Tripod is a meteorological observation tripod tower that can be easily and rapidly installed using fixed post without cement placing for fixing. Prepare essential tools for the installation of tripod support. Besides, use pliers or long-nose pliers for easy work. 4.3. Assembly of tripod support Tripod support consists of the below bulk product and parts for easy movement and site installation. 4.3.1 Component.
13
4.3.2 Assemble tripod support in the below order. ① Insert support (top) to bracket where support (bottom) is mounted. ② Assemble 3-direction hinge of center support using included bolt, nut, flat washer and spring washer. (※ Fasten bolt and nut loosely so that it can be adjusted) ③ Insert central pole to assembled tripod support pipe.
14
4.4. Bearing setting To set base direction setting of wind direction sensor, find true north. To set true north, find magnetic north using a compass, and calibrate by magnetic declination between magnetic north and true north, and mark true north. Magnetic declination varies by latitude and longitude. For Korea, magnetic north is located at 6˚ ~ 8˚ from the west of true north Find magnetic north using a compass, and rotate it to east (clockwise direction) at 6˚~8˚ to set true north. Magnetic declination by resion (θ) Seoul, Gyeonggi, Incheon, Gangwon, Ulreungdo: Chungcheong, Jella, Gyeongsang: Jeju Island:
8˚ 7˚ 6˚
4.5. Installation of tripod tower ① Flatness work: Make the surface flat with 3 support points of tripod support. ② Mark true north on the surface. ③ Stretch tripod support, put one support to true north, and adjust minutely to make
flat. ④ Drive fixed pole: Drive fixed pole into ground Keep tripod tower location and flatness and be careful not to damage foot. ⑤ Check flatness and fix bolt: Check flatness once again and fasten bolt and nut. Apply silicon grease to prevent rust when disassembly is necessary later.

5.4. Logger unit installation Fix logger unit at the central pole end of tripod support temporarily. Attach solar cell module on the unit front cover and fix it. Set the light collection surface of solar cell attached to logger unit to the south direction. Height can be adjusted for the user convenience.
5.5. Earth bar installation ① Connect earth line with 1m Earth bar by using combining plug. ② Set earth bar installation locate near the installation of tripod support, and dig
ground suitably. ③ Drive earth bar deep into ground using a hammer so that earth bar head is not seen. ④ Cover soil and flat the ground.
5.6. Cable connection ① Combine Data logger and Sensor by using cable. ② Connect output line of light collection plate of solar cell with charging part.
Before power supply to the equipment, check if the output polarity and data logger polarity are identical and connect carefully.
5.7. Communication module connection ① Communication supports RS232 and RS485. Use proper wired/wireless communication method. ② For connection to optional Bluetooth wireless module (SWDL-8020) or Zigbee wireless module (SWDL-8021), refer to attached CD and manual.
6. Inspection and measurement 6.1. Power inspection and measurement ① Power is divided into 12 V battery without using heater, and 24 V external power with heater. ② Heater is operated under 4℃ at outdoor temperature. ③ If LED light of data logger is not turned on, check power cable connection and
battery amount.
6.2. Communication inspection ① If communication is not available, check if communication port of data logger is set properly. ② Check if spot number set in collection PC and communication port are identical.
