EXPAND (X1) is full horizontal display scale
displaying channel zero to channel 1023.
EXPAND (X2) is operated in conjunction with the MEMORY
switch. With the MEMORY control set in the 1/2, 2/2 or
FULL position, then HORIZ (X2) will display as follows:
MEMORY: 1/2 - (X2) will display the first half of
the memory in full horizontal scale.
MEMORY: 2/2 - (X2) will display the second half of
the memory in full horizontal scale.
MEMORY: Compare - (X2) overlays first 1/2 on
second 1/2.
EXPAND (X5) position expands the horizontal display by a
factor of 5. Therefore, any block of 205 channels may be
displayed full scale by utilizing the (X5) position in
conjunction with the HORIZONTAL POSITION control.
INTEGRATE MODE consists of the following controls:
CURSOR, plus the options FLAG, ERASE and START/STOP.
FLAG ERASE/ON/OFF toggle control for clearing the
region(s) of integration or any other region that
was set up.
START toggle position, when depressed, intensifies
the channels to the right of the cursor, defining
the start of the region to be intensified.
STOP toggle position, when depressed, de-intensifies
the channels to the right of the cursor, defining the
stop channel of the ROI.
NOTE: The cursor must be moved between the Start and
Stop toggle operation for defining each region.
After region is set, cursor is free for other
operations, except when multiple ROT option is
on. Then, cursor is used to define which ROT
is to be integrated or readout. All channels
between the Start and Stop locations will be
intensified for ease of viewing.
The INTEGRATE MODE function enables the user to select
region(s) of interest within an accumulated spectrum for
total count determination and readout. (For an explanation
of the required procedure in setting up a region of interest,
please refer to Section III, MODE: INTG.)
