    Besides the mechanical protection, the optical properties of the glass dome minimize the undesired influence of long wave radiation on the shortwave radiation: the dome of the EKO pyranometers is 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.

    If the pyranometer is not levelled properly, the pyranometer readings are affected by cosine and azimuth errors. Periodically check the spirit level and adjust the pyranometer’s position if necessary. EKO INSTRUMENTS CO., LTD. - Pyranometer MS-40/40S - Instruction Manual Ver. 4 Pg. 13...
  • Page 14 *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. In the case of MS-40S, it is possible to acquire tilt information obtained from the built-in tilt sensor through Modbus RTU.
  • Page 15 Connect the output cable, DC power supply [5 to 36 V], and ammeter as shown in the figure below. Install a fuse [0.5A] in series between the DC power supply [+] and the MS-40S connection as shown below for over current protection.

    1,400W/m in both horizontal and tilted measurement positions. When this is converted into MS-40S output, the result will be 20mA [default]. The output for the MS-40S [4-20mA output] is set to be 1,600W/m at 20mA.
  • 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].
