S, In the field of [Measure(ohm)] shows "OPEN".
Line A/B Bad Impedance
If the value of Measure (ohm) is greater than Reference A&B (ohm) + Tolerance (%), or value of
Measure (ohm) is less than Reference A&B (ohm) - Tolerance (%), this fault can be recognized
by IDA8C/S. In the field of [Diff(%)] shows the percentage of difference, in above figure, the
difference percentage of zone 4 is 78.24 which is great than the tolerance 15%, a Line A/B bad
