CES
When a continuity failure occurs, the Continuity Error Scan mode causes the system to perform a bulk scan on the input address automatically. The all-points isolation scan uses the current continuity parameters unless a parameter set is specified in the command (see Syntax Usage below) to find and record all points outside the current string connected to the input address. Without CES, the system records a failed continuity test in the test results log and resumes with the next test.
