After I installed DataField, I got two desktop icons: DataField CS and DataField Online. Which one do I use?
DataField OnLine is an online service that must be purchased separately from the instrument. If you have not contracted for DataField Online (also called EnviroComp), then you can ignore or delete the “DataField OnLine” icon. The icon itself is simply an Internet shortcut to the EnviroComp site hosted at LANDTEC. DataField CS is software that runs on your own computer, and works without any additional purchase. It allows you to create and manage Well ID lists, download field readings and change settings. You cannot use your GEM-2000 without DataField CS.
