What is the maximum fixture test area?
There is no real limit for the physical test area. If parts are larger than the pad on the AT3600 fixture Kelvin leads can be extended to accommodate larger parts with a fixture separated from the tester . The central test pad area is 4" by 4" but this is not a hard limit for a transformer size.
There are total of 20 nodes available but if additional nodes are required a relay controlled by an OUT test may be used via the USER interface.
Please see Thread 1649 for details on using the User port and OUT tests.
Please see Thread 1654 for using extended Kelvin leads to external fixtures.
