control is required for this test system, therefore, the grading mode must be used.

Binning system multiple-element devices
Digital output clear pattern
After every binning operation, the digital output needs to be reset to a clear pat-
tern, which serves as a no action condition for the component handler.
The SourceMeter can be programmed to automatically clear the digital output
after the pass or fail pattern is sent. With auto-clear enabled, you can specify the
required pulse width (delay) for the pass or fail pattern. (The default auto-clear
pulse width is 10µs.) When not using auto-clear, you must return the digital output
to its clear pattern from the DIGOUT AUTO CLEAR option of the CONFIG LIMIT
menu. This option also sets the pass/fail pattern and pulse width.
