    ET107 Weather Station Introduction The ET107 is an automated weather station designed for irrigation scheduling in turf grass and commercial agriculture applications. A properly programmed station calculates potential evapotranspiration (ETo), which is the amount of water lost from the soil due to evaporation and plant transpiration. Calculating the evapotranspiration rate can aid in the development of an irrigation schedule that provides sufficient water without overwatering.

Push up on the small Phillips screw underneath the mechanism and slide it to the left. Once in place, put a small wire tie in the hole to the right of the locking mechanism (see FIGURE C-8).
  • Page 93 FIGURE C-9. Fully mounted solar panel Throw a blanket or box over the solar panel to prevent any voltage output. Route the solar panel cable and power cable coming from the main ET107 enclosure into the conduit at the bottom of the 10-inch-by-12-inch enclosure.

  • Page 95 NOTE The power cable that carries the regulated 12 Vdc power from the regulator in the external enclosure to the ET107 station enclosure has a two-pin connector on one end and tinned wires on the other. 13. Toggle the power switch on the regulator (CH100, PS100, CH150, or PS150) to the OFF position.
  • Page 96 Pink on the humidity indicator card means it’s time to change the desiccant. Change the desiccant at least every year. However, it’s often wise to change the desiccant every six months. 23. Close the lids on the external enclosure and the ET107 enclosure. C-11...
