Send
Save the spectrum and go to
Send Spectrum
(see

), avoiding the detour around the
normal options menu hierarchy. The current spectrum will be already chosen for sending.
Preset
Go to the
Presets
(see
6.8

Calibration
The calibration check screen (Figure
122
, p.
116
) shows a zoomed spectrum (see
6.2
, p.
106
) of a
certain peak and some parameters describing the peak. The center of the horizontal axis is posi-
tioned at the theoretical peak position and the vertical axis is scaled logarithmically.
Upon entering this screen, a peak of
137
Cs is shown. You can choose other nuclides from a list of
nuclides commonly used for calibration (Table
1
, p.
115
).

, p.

for details about the nuclides.
Make sure the source selected to be checked is present when using this command.
For best results, move the instrument to a low-radiation environment to check the calibration.
Data for this spectrum are continuously acquired beginning with an empty spectrum upon entering
this screen or after you cleared the data (see below).
