Page 3: Specification
Specification POM-02 Skyradiometer measures circum solar radiation and spectrum intensity of the direct solar radiation for the research of the size distribution and concentration of the aerosols. In addition to the feature of POM-01, POM-02 also measures the long wave length. -
Page 4: Installation Procedure
Installation Condition of the installation Skyradiometer shall be installed under the clear sky (Sun sensor need to react during the installation) Mount the tracker on the sold and flat place, with free field of view, especially in the direction of East-South-West. - Page 5 NOTE: Connector 4, 5, 6, 7 are the single lock type. Align the guide of the plug and receptacle, and push the plug straight until it makes the “click” sound. (5key type of guide can be easily aligned by slightly rotating the plug) NOTE: Do not twist the lock nut, when inserting the plug.
- Page 6 4. Adjust the horizontality of the skyradiometer by using a water bubble on the leg of sun tracker. It is necessary to maintain the sun tracking accuracy. 5. Fix the skyradiometer on the mounting base, by using 3 pieces of screws, included in the package. NOTE: It is necessary to fix skyradiometer to the flat and robust mounting base, for the fall-prevention against the strong wind.
- Page 7 7. Connect the Communication cable(RS232) and Power cable (AS3P). NOTE: Prior to the connection of the power cable, make sure that there would be no obstacles around the skyradiometer, since it automatically start the origin search movement, immediately after connecting the power cable.
- Page 8 11. Make sure that the sun light is on the center of the target. Skyradiometer might not track the sun correctly in case the position of the sun light is far out of the center. NOTE: Do not touch to the target. 12.

OS: Windows XP / Vista / 7 (32bit/64bit) POM02_SET ********.exe, and configure the observation program. First of all, execute the NOTE: ******** is the version of release (Updated date) Folder will be automatically generated at the directly of C:¥pom-02¥data C:¥pom-02¥obs Setting Screen ※１ ※2 NOTE: Configure the following items at the setting screen. - Page 10 (Files to be generated : .sun, .data, .cld) Example: In case the storing directory was set as C:¥POM-02¥Data, folder will be generated automatically with each date, and the data will be stored with the file name of observation date, such as C:¥POM-02¥Data¥20160315. Configuration of measurement data : Set the method to generate the measurement data.

Page 11: Standard Operation
Specification of the operation Standard Operation Followings are the specification of the skyradiometer’s movement (Numeric values can be modified in the Setting Screen) 1. Start (end) of the observation : Start at Airmass <=10 (Start) Airmass＜=10 (End) Airmass＞=10 Ex.Observation Starting/Ending Airmas ＝10 2. - Page 12 3. Direct sun observation interval : Time (60 sec) 4. Direction of Aerosol observation : Observes horizontal direction of east and west alternately. However, skyradiometer observes vertical direction (Zenith to North) when the sun altitude exceeds 75 degrees. 1st observation 2nd observation φ=0 φ=180...
- Page 13 Disk scan schedule : Disk scan schedule (interval, day and time) can be modified in the setting screen. (Default: every 7 days, 10:00a.m.) Each wavelength with the check in the “Disk” of Wavelengths Setup will be scanned once, when the sky is clear and time reached to the set time Time Correction of the tracker : 23:00 (Every day) : synchronize the clock of the tracker and PC.

This process is recommended when the skyradiometer was relocated and re-installed. Adjust the values of Azimuth center and Altitude center within +/- 0.050, by the screws.
- Page 19 Disc Scan Screen Graphic display will be automatically switched and the Disk Scan results will be displayed. Please carry out the Disc Scan on the regular basis (Periodically) Automatic disc san is available by the setting on the observation program. NOTE: X-Scan needs to be carried out under the clear sky.
