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.

常见问题解答

ET107: 18

  1. How can the ET107 RH chip be replaced?

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

  2. Does the ET107 have heating capability for snow accumulation and a snow screen?

    No.

  3. Is the ET107 compatible with Calsense controllers?

    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.

  4. Is the 6182 the replacement battery for the ET107?

    Yes.

  5. Can communication be initiated with the ET107 using Modbus?

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

  6. What is the difference between the ET106 and the ET107?

    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.
  7. Can 24 Vac work with an ET107, or does it have to be 16 Vac?

    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.

  8. Is the VisualWeather software included with the purchase of an ET107?

    No. VisualWeather must be purchased separately.

  9. Can a leaf wetness sensor be added to an ET107?

    No.

  10. What methods of communication are possible with the CR1000M included with the ET107?

    The communications options include direct serial connection, short haul modem, analog phone modem, cellular phone modem, radio, and Wi-Fi.  Also, with an enclosure alteration, an Ethernet port can be added.

    Note: Some of the listed telemetry options can drastically alter the power budget of the station.
