2.5.7. Status
Figure 15 shows the Status tab.
The Enable Counter functions
when the Gate function on the
ADC tab is set to Event and the
digiBASE is actively acquiring
data in a spectrum. Under these
conditions, the Enable Counter
accrues the number of events at
the ENABLE INPUT since the
Start command was issued. To
clear this counter, click on the
Clear Spectrum button on the
MAESTRO toolbar or issue
Acquire/Clear.

2.5.8. Presets
Figure 16 shows the Presets tab.
The presets can only be set on an
MCB that is not acquiring data
(during acquisition the preset field
backgrounds are gray indicating
that they are inactive). You can use
either or both presets at one time.
To disable a preset, enter a value
of zero. If you disable both presets,
data acquisition will continue until
manually stopped.
When more than one preset is
enabled (set to a non-zero value),
the first condition met during the
acquisition causes the MCB to
stop. This can be useful when you are analyzing samples of widely varying activity and do not
know the general activity before counting.

The Aux0 and Aux1 counters are reserved for future use.
