Probe card removal procedure
Hazardous voltages may be present on an installed probe card even after the output is
disconnected, that if contacted, may cause personal injury or death.
Never attempt to touch or change a probe card when tests are running. You must be
absolutely certain that all tests have stopped before making contact with anything in the
vicinity of the probe card adapter. Also, never run tests without a probe card installed.
To remove the probe card:
1. Turn the vacuum control box valve to the unload position.
2. Release the probe card retainer cap latches.
3. Carefully remove the probe card and retainer cap from the probe card adapter.
