Z1800-Series Operator’s Guide
To set up for static safety:
•
Connect the antistatic floor mat to the tester.
• Use the operator’s wrist strap.
•
Wear proper clothing.
• Eliminate static producing materials from the work area.
See “Using the Tester Safely” in Chapter 1 for more information on static prevention and
control.
Note:
Z1800-Series manuals are bound in static-dissipative binders. They will not store an
electrostatic charge and are safe to use near sensitive electronic components. Teradyne
recommends against making copies of pages for use around testers—photocopies may
carry electrostatic charges.
Check the Printer Check that the diagnostic printer is working properly, and that it has enough paper. Inspect
the paper-feed mechanism for paper-feed jams. See the printer manual for further
information.
Inspect the Fixture Fixtures require regular inspection. Inspect the fixture at least once a day. Inspect it more
often when the production environment dictates. Use a soft brush and compressed air to
keep the fixture’s surface clean and free of dust and contaminants. A clean surface ensures
that the fixture accurately contacts the board-under-test.
