To return to a previous zoom level, make selection of any fragment of the spectrum from left to
right so that the mouse cursor be positioned beyond the boundaries of a field, displaying the spectrum,
and then release a button.
In the bottom right corner, there are two buttons to start a new spectrum accumulation (Restart)
and stop/continue it (Pause/Continue). After opening the Expert mode window spectrum
accumulation starts automatically. This process is indicated by a blinking EXCHANGE label under
the Restart button and a green colored group in the bottom pane of the window with a name of the
unit and its serial number. When acquisition is finished, the color of this group turns red.
The Cursor group provides more detailed information about a spectrum channel the cursor
points to:
Channel – indicates the number of the channel the cursor points to.
Energy – indicates the energy corresponding to that channel.
Value – indicates the number of pulses in this channel.
Except for this, this group includes two buttons (<< and >>) that allows moving the cursor more
accurately.
In the upper right corner there is the drop-down File menu through which you can save a
received spectrum (Save), open a previously saved spectrum for viewing (Open) and close the
Expert mode window (Exit).
