APPENDIX B:
Atomlab Display Diagnostics
For 400/500 Series
Overview
The nine button black & white Atomlab 400 and color touch screen Atomlab 500 for the new
generation of Atomlab products have built-in boot-up self-diagnostics, along with real-time
monitoring of the detector statuses. The detectors themselves have real-time self tests, the
results of which are reported back to the display approximately once per second. Dose
calibrator detectors and Well counters are the two types of detectors supported.
The results of the display module’s self-test are displayed during the display’s power-up, as well as
on-demand, shown on the system test screen under utilities, in the upper section of the
display results. in addition, during normal operation detector status changes are handled by the
display, reported on screen with a popup screen and audio tone alert, and actions taken based on
the severity of the reported status.
The System Test Screen Displayed Results Are Divided Into Two Sections:
• Upper half is the display module’s details (static result from boot-up)
• Lower half lists diagnostic and status results for each identified detector, up to 7 on an
Atomlab 500. Dynamically updated in real-time, about once/second
Real-Time Operating Detector Status Changes
During the course of normal operation, detectors report their status constantly to the display
unit, including any detectable error conditions. The status reports come in as long the power to
the display remains on, the detectors stay connected, and not in a severe fault state
(communication error). so this means even if the detectors are not being used, or the display is
blanked from the screen saver, the detectors are still communicating and being monitored.
For all newly reported error statuses, a detector or detector status error reporting screen will
appear with an audio tone to alert the user. an error code will be displayed with its brief
description. If WARNING is displayed next to the code, it indicates the detector is still usable. If
Fail is displayed next to the code, the detector will automatically be dropped from being
selectable by the user. For an Atomlab 500 with multiple detectors, the next available detector
will automatically be selected. If there are no available detectors, the activity readings displayed
will be dashed out and activity screen will indicate no available detector, or detector error.
For “Detector Leaking Gas” or “Detector Gas Low” warnings, there is a 24 hour reminder warning
implemented. If either of these warnings is in effect for a connected detector, every 24 hours the
detector or Detector Status screen will display with this warning code and description. All the 24
hour reminders are scheduled to appear 8am, and only if 4 hours elapsed since the
warning was first detected and displayed.
