Page 7: Introduction
The MS-56 has a standard full 5° (degrees) opening angle and 1° slope angle as defined by ISO Pyrheliometers Standards and greatly performs when used in combination with the EKO STR-21(G) or STR-22(G) Sun Tracker. -

Installation In this application the MS-56 is mounted on the EKO Sun Tracker STR-21G/22G, which is a fully automatic sun tracking system supporting solar sensors capable of measuring Direct, Diffuse and Global radiation. X/Y-Axis... - Page 11 2. How to Replace the Mounting Plate (Optional) When installing MS-56 on EKO Sun Tracker STR-21G/22G, 3-hole mounting plate is required. If you already have EKO Sun Tracker purchased before July 2011, you need to purchase the “3-hole mounting plate” (optional part) separately for installing MS-56.

- Page 13 In order to measure the solar irradiance, the MS-56 should be connected to a measurement device, in most cases a data logger. MS-56 is a passive sensor that does not need any power; however to operate the window heater, a DC12V (0.5W) power supply is required for heating.
- Page 14 4. Sight Spot Adjustment In order to take an accurate measurement, MS-56 has to be aligned with the sun properly. When the sky is clear, the sun light will go through the sight and a spot of light is shown on the sight spot surface of body top.

It is recommended to use the window heater to prevent dew deposition at the Quartz window. Turn on the heater at least 30 minutes before sunrise. -

A response time of less than 1s to achieve 95% of the final measurement value is one of the unique features of the MS-56. The small thermopile detector having a low heat capacitance and high thermal conductivity responds quickly to changes of the solar radiation. To keep the detector-output stable and in perfect thermal balance during changing environmental and solar radiation conditions, the detector body is isolated from the sensor housing. - Page 22 In general the sensitivity of optical detectors depends on the temperature of the instrument because of material properties, known as the temperature coefficient (TC). However the MS-56 sensor construction has a built in special passive compensation network which reduces the temperature dependency to less than +/-0.5% between –20...
