Figure 55 Zone Settings Screen for a Gamma Detector
There is an individual setup screen for each detection zone, including singles, pairs,
triples, etc. The screen title shows the description (head, foot, body, etc.) as well as,
in the case of sum zones, the single detection zones that make up zone currently
selected. Its location is indicated on the inset layout diagram by hatch marking. The
number in small font at the top right of the screen gives the sequential number
assigned to the zone that is used on various information screens and printouts. Use
Ctrl+Home, Home, PgDn, PgUp, End or Ctrl+End to select the first, first in the
group, next, previous, last in the group or last zone, respectively. Pressing Home or
End repeatedly advances quickly through singles, pairs, triples, etc.
The screen background is dark green for Gamma values.
