To check the power-up tests
The logic analyzer automatically performs power-up tests when you
apply power to the instrument. The revision number of the operating
system shows in the upper-right corner of the screen during these
power-up tests. As each test completes, either "passed" or "failed"
prints on the screen in front of the name of each test.
1Disconnect all inputs, then insert a formatted disk into the
flexible disk drive.
2Let the analyzer warm up for a few minutes, then cycle power by
turning off then turning on the power switch.
If the analyzer is not warmed up, the power-up test screen will
complete before you can view the screen.
3As the tests complete, check if they pass or fail.
The Flexible Disk Test reports No Disk if a disk is not in the disk drive.
