To degauss the display
If the logic analyzer has been subjected to strong magnetic fields, the CRT might
become magnetized and display data might become distorted. To correct this
condition, degauss the CRT with a conventional external television type degaussing
coil.
To clean the logic analyzer
With the instrument turned off and unplugged, use mild soap and water to clean the
front and cabinet of the logic analyzer. Harsh soap might damage the water-base
paint.
To test the logic analyzer
• If you require a test to verify the specifications, start at the beginning of chapter 3,
"Testing Performance."
• If you require a test to initially accept the operation, perform the self-tests in
chapter 3.
• If the logic analyzer does not operate correctly, go to the beginning of chapter 5,
"Troubleshooting."
