ET107 Default Programs (4 KB) 29-03-2021

One default program is for an ET107 with the 034B wind sensor and another default program is for an ET107 with a WindSonic1.

ET107 ETsz Example Programs (290 KB) 23-06-2021

The ETsz() instruction requires the user to input lattitude, longitude, elevation, and crop type for a station's location in order to generate accurate calculations of ET. The Generic_ET_107_ETsz.CR1 and Generic_ET_107_ETsz_Windsonic.CR1 programs use the ConstTable() intruction to create a constants table that allows the user to easily input these values using Loggernet, PC400, or a keyboard display. These values only need to be set once, during station set up.

ET107: 18

  1. Refer to the “Maintenance, Troubleshooting, and Schematics” section of the ET107 Weather Station Instruction Manual for procedural instructions.

  2. Calsense Command Center software can interface with Campbell Scientific’s VisualWeather software, which can retrieve values from the ET107. In the Command Center software, setting up a station involves connecting to the VisualWeather LoggerNet server and selecting variables from the weather station’s listing for wind speed, rainfall, and ETo.

  3. The PS100 power supply that’s in the ET107 specifies a charging voltage of 15 to 28 Vdc or 18 Vac RMS.  A 24 Vac transformer will blow the protective circuitry in the PS100.

  4. Yes. However, special data logger programming is required. Contact an application engineer at Campbell Scientific for assistance.

  5. The most significant difference is that the retired ET106 used the CR10X datalogger, whereas the ET107 uses the CR1000 datalogger. Other differences are the following:

    • As a design improvement, the ET107 has a seal incorporated into its lid assembly.
    • The ET107 uses a CS300 pyranometer instead of the LI200X pyranometer.
    • The ET107 provides a choice of wind sensor (either the 034B or the WindSonic1), whereas the ET106 could only be used with the 034B.
  6. No. VisualWeather must be purchased separately.

  7. If VisualWeather is used with the ET107, T107 (Toro), ET106, or MetData1, and the station has a standard configuration, setting up the station in VisualWeather is relatively simple. Select the station from the list in the Weather Station Network screen, and most of the work is automatically performed.

    If, however, a custom station, a different station model, or a different variation for one of the sensors is used, it is necessary to set up a custom station in the Weather Station Network setup screens. In the Station Selection screen, select Custom.

    Follow the screens that ask about the details of the station. Then, VisualWeather will connect to the station and get the names and fields of the data tables on the station where the data is stored. Because the names and fields of these tables are meaningless to VisualWeather, a mapping process must be used to map data table fields to fields and units that VisualWeather recognizes. This mapping allows VisualWeather to create screens and reports that are meaningful.

    Because the data tables are often identified with a number and the fields are often cryptic, the mapping process can sometimes be confusing. To map fields for a custom station, contact Campbell Scientific for assistance.
