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.
1
Disconnect all inputs, then insert a formatted disk into the flexible
disk drive.
2
Let the instrument warm up for a few minutes, then cycle power by
turning off then turning on the power switch.
If the instrument is not warmed up, the power-up test screen will complete
before you can view the screen.
3
As 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.
