If a meter has been switched out and/or disconnected, indicate the disconnection date inside the Meter Editor. If the meter truly never existed or if you have an entered data error, delete the meter. To do this, take a look at the Summary tab. You'll see the list of meters in a table in the bottom half of the screen. Identify the meter you would like to delete and select the down arrow menu button for that meter. Select "Delete Meter" to remove the meter from the site.
