When there is at least one recording in the device's memory, that recording can be analyzed by using
the AQviewer software (see the image below). However, the recording must first be made accessible to

By default, the default plotter is empty. Choose the measured signals ("Analog channels") on the left to
move them to the plotter. In the image below (on the left) the phase currents IL1, IL2 and IL3 are
selected; AQViewer color-codes them automatically. If you want to add another plotter, choose the blue
"+" icon (in the main toolbar on the top). Please note that the "Add plotter" text appears when you move
the cursor on top of the icon. Once clicked, the "Add graph" pop-up window appears (see the image
below on the right). In the example the line-to-neutral voltages UL1, UL2 and UL3 are selected and
moved to the window on the right. Confirm the selection by clicking the "OK" button.
