Counting the numbers of units passing or failing
(HP 54656A only)
The external output lines from an HP 54656A can be used to count the
number of tests, the number of units passing, and the number of units failing.
A simple counter IC can be used to count the number of occurrences.
Normally, a counter IC requires an edge for counting. The counter counts
the results of the testing when the operator hits the Next switch.
The Output line, which is defined as Pass or Fail, should be ANDed with
another output line defined as END in order to serve as the input to the
counter IC.
Example of a circuit for counting the occurrence of pass or fail using the output lines
