Unique to AEM field testers, is the ability to get a TDR trace of shield continuity. For shielded cable applications, being able to find the distance to where the shield continuity has been compromised is critical. Combination of impulse TDR and step TDR traces make it easy to find even small problems with the shield. Testers which only measure basic shield continuity will not detect a compromised shield issue like a “partial discontinuity” (a small part of the shield is still  maintaining contact, but it has been otherwise damaged/compromised/not fully connected).

Shield Discontinuity alert will be indicated on Wiremap after the test, with an indication of distance to the event, the user can then go to the Shield Locator tool to view the TDR trace of the shield, with a clear indication of the location of the discontinuity.
