any test limit. See Chapter 6.)

PASS*/FAIL* Results

A result shows an asterisk when measurements are in the tester's
accuracy uncertainty range (Figure 20) and the asterisk is required
by the selected test limit. These results are marginal.
 A PASS* shows that the cable's performance is
satisfactory. If a cable must get a PASS result to agree with
your requirements for quality, identify and correct the
problems with the cable and do the Autotest again.
