5.4.1 MCA Presets
When P RE A DJ (F4) is selected, the presets are displayed in the data area. When the presets are dis-
played, the F4 function key changes to read HW A DJ (or HW I NFO when not in Manual mode). The SAM
935 has the following types of preset controls:
ON/OFF When the preset enable is set to OFF presets will have no effect. It is the
same as setting all presets to zero.
LT Pre Preset live time.
RT Pre Preset real time.
Pk Pre Preset peak count.
Int Pre Preset integral.
If you are in the manual MCA mode, the presets may be adjusted from this screen. Pressing the
↓
and
↑
arrows moves from preset to preset. The currently selected preset is displayed in the message line. Use
the
←
and
→
arrows to change the value of the selected preset.
Note: Preset live and real time will be exact, while in preset peak and integral, the actual
values may exceed the preset slightly.
