A: The GEM500 does not support the full range of features that the GEM™2000 does, such as custom pump running time, info labels and custom questions. If you create a Well ID list using these features in DataField , then upload the list to the GEM500 and subsequently download that same Well ID list, you'll find that the non-supported features are gone. The correct way to handle Well ID lists is to create them in your instrument communications software and save them in files on your computer, thus ensuring that the list is not lost. Then when the Well ID list is needed, load it into the software, then upload to your GEM500 and/or GEM™2000 instruments. The GEM500 only interfaces with DataField; the GEM™2000 interfaces with both DAtaField and LSGAM. When you use LSGAM (GEM™2000), because the list is already saved on your computer, you will never have to download it from the instrument. If you are interfacing with DataField (GEM500), save your IDs on your computer.
A: The well IDs must have 8 characters—that's letters or numbers, no punctuation. A commonly used technique is to use a four or five letter abbreviation for the landfill, followed by a three or four digit zero-prefixed well number. So, if you own the Smith County Landfill, you might identify your wells as: SMITH001, SMITH002, SMITH003 and so on.
A: The Well ID list you created in the communication software was not automatically saved on your computer. To save a copy on your computer so that it is available for uploading to an instrument later, create the list, then click on the "Save File" button on the Well ID screen and choose a folder and filename that will allow you to find it later. If you created a Well ID list, then uploaded it to an instrument but did not save it on your computer, you can recover it in LSGAM by going to the Well ID screen and clicking "Load from Instrument". The list will be loaded into LSGAM, at which point you should click "Save File" as described above. Your Well ID list needs to be saved to your computer only once. In DataField you need to save your IDs in a file; otherwise you will loose them. LSGAM will automatically save the IDs in a file under the project name. That file will be there every time you open LSGAM.
