4. Introduction Sky Scanner MS-321LR is designed to measure luminance and radiance using sensor with 11 degree aperture angle and dual-axis control driving part by dividing the sky hemisphere into 145 points. 4- 1. Mai n F un c ti ons 1. Sky Scanner MS-321LR tracks the sky hemisphere by dividing it into 145 points, measuring luminance and radiance in 4.5 minutes using the sensor with 11 degree aperture angle and dual-axis control driving part. The measurements of 145 points are based on the CIE108-1994 recommendation. (CIE - International Lighting Commission, IDMP - International Daylight Measurement...

Driving Part Base structure to mount the Sky Scanner. Spirit Level For leveling the Sky Scanner in a horizontal position. Leveling Screws Directs optical sensor to the 145 measurement points that are defined by altitude and azimuth angle of sky hemisphere. Adjustable screws to position the Sky Scanner in horizontal position. Use these screws to bring air bubble to the center of spirit level. For fixing the...

Installation Location & Setup Conditions Install the Sky Scanner in a place where nothing obstructs the view of the sensors. The ideal mounting position for Sky Scanner is a location which has a free field-of-view without any obstructions (such as buildings, trees, and mountain). In practice, it might be difficult to find such locations; therefore, some practical recommendations on how to minimize undesired effects of reflecting or obstructing surfaces are given next:  Select a mounting position which it is free from obstructions at 5° above horizon. The setup location should be easily accessible...

Preparing Installation Base Prepare a setup base with fixing holes for the anchor bolts (M8) as shown below. installation position will be important, thus carefully check the position of the anchor bolts. Make sure that the mounting base can hold total weight of the Sky Scanner itself and the sensors mounted on the Sky Scanner. The anchor bolts must be attached to hold the Sky Scanner on the setup base. To avoid unexpected accidents or damage due to strong wind or gale, make sure to fasten the tripod on the stage or ground securely. Figure 5-3. Anchor bolt position Put Sky Scanner on the installation...

2) Adjust the leveling screws to setup the tripod in horizontal position. Use the leveling screws to bring the air bubble inside the spirit level in the center of the circle indicated. 3) Once the position and horizontal level for the Sky Scanner has been completed, fix the Sky Scanner securely onto the mounting base using attached M8 bolts. 4) Attach the optical sensor on the mounting plate. After placing the optical sensor on the V-block attached on the mounting plate, secure the optical sensor with attached fixing rings. 5) Install personal computer in a safe and suitable area.
