  • Page 11: Getting Started

    Besides the mechanical protection, the optical properties of the glass domes minimize the undesired influence of long wave radiation on the shortwave radiation: the domes of the EKO pyranometers are only transparent for radiation emitted by the sun. Hence they block the undesired infrared radiation emitted by the Earth’s atmosphere.
  • Page 12 Durable materials are used for the cable and connector, and pin terminals are attached at the end of the cable for easy connection with data logger terminal block. * If longer cables, round terminals or fork terminals are required, please contact EKO Instruments or your distributor. [Also see [7. Specification, 7-4. Accessories List] for optional items.] The connector should be protected by the self-fusing tape when the pyranometers are used in the areas with the risk of the salt damage.
  • Page 13 The sunscreen can be removed by loosening the knurling screw and sliding it towards the spirit level direction. *When carrying the MS-60 with sunscreen attached, always hold the instrument from the bottom. Holding only the sunscreen part may lead to dropping the sensor as it comes off from the sunscreen.
  • Page 14 [Installing at Tilted Position] After the MS-60 is adjusted to horizontal position in levelled surface, install it on tilted mounting position. *When installing the instrument, do not remove the levelling feet or fixed feet; if the levelling feet are removed, it may cause abnormal output values due to the thermal effects from the mounting part.

  • Page 19 The maximum output voltage can be calculated by multiplying the maximum solar irradiance with the calibration factor [e.g. when the sensitivity of the MS-60 pyranometer is about 10μV/W・m 0.010mV/W・m , the maximum output voltage is about 1,400W/m times 0.010mV/W・m...
  • Page 20 Hence, sampling rates and data reduction methods can be defined right at the beginning of the data acquisition process. The response time that is given in the specifications of the EKO pyranometers states the amount of time, which is necessary to reach 95% of the final measurement value. It is also possible to define a 63.2% response [which is equal to 1-1/e].
