HP 1660 Series User Manual

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.
11
Disconnect all inputs, then insert a formatted disk into the disk drive.
22 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.
33
As the tests complete, check if they pass or fail.
The Front Disk Test reports No Disk if a disk is not in the disk drive.
