The detector parameters on the Detector Setup tab provide the user with the ability to
view and configure high voltage power supply parameters for the detector. The
detector has the ability to read and write any of these parameters as requested by the
user. When the system is shut down, the last stable high voltage control information
will be used at the next startup.
Each detector can utilize up to two high voltage power supplies.
1. The Force Hi Voltage #0 Hold Value dropdown provides the user with the option
to place the detected high voltage power supplies in hold mode.
a. If Yes is selected, the system will hold the high voltage at the value designated
in the Hi Voltage #0 Value textbox.
b. If No is selected, the system will use live system data as the Hi Voltage #0
Value.
2. The following fields are intended for display only, however, the user has the ability
to modify the values in these fields.
Last HV Control Time Constant
•
Last CPLD Window Count
•
Last Board Temp ºC
•
Last Hi Voltage #0 Control
•
Last Hi Voltage #0 Setup
•
Min CPLD Channel 1 Window Count
•
Warning: Making changes to these parameters may cause the system to
become unstable.
The Count tab displays the specified detector counts in a graphic representation.
