Test sequence

Click Calculate Time to get an estimate of the time it will take to run the selected diagnostics.
Click Run to initiate the test.

Note: Do not change the Test Options settings from the default settings unless instructed to do so by a GE Healthcare engineer. There are very few circumstances when these settings need to be changed.

Topic ID: id_SL1914835-1280246

Results

Diagnostic results display a status of Pass or Fail. If you receive a Fail status, click GE System Log to view the error message. The system log records errors with the date, time, the process tested, and a detailed error message.
