• Sample and Reference Rings are in series with one
another and a controlled current source.
• Each Ring Pair operates independently from other Ring
Pairs (allows redundancy).
• For each measurement cycle, current is injected in Mode
0 (4sec), then switched to Mode 1 (4 sec).
• Total measurement cycle is approximately 10 seconds.
• Real time calculation of Metal Loss per sector
