Specify which meter list you wish to work with. For more information on how to do so, see the section "Specify which meter list you wish to work with".
Go to the meter list (see image below).
Click the tab within which the meter you wish to open is available: "Main meters", "Sub meters", "Virtual meters" or "All meters" (see image below). Note that, in the list "Indirect meters" there is no tab for main meters.
Filter the meter list if you wish to limit its contents (see image below). For more information on how to do so, see the section "Filter the meter list". If you do not wish to filter the meter list, you can skip this step and go straight to step 5.
Click the meter you wish to work with (see the first image below). The meter you click will open. When a meter opens, so does its meter card (see the second image below). Via the meter card you can work with a meter.
