[Test-Equipment] Fluke 8500-series DMM question.

[Barry]

Anyone familiar with the Fluke 8500-series DMM?  I have an 8502A and the manual talks about using a "Bus Interconnect and Monitor Board, MIS-7013K" in the calibration sections but I can't find any information on that accessory.  I assume its some kind of bus extender to allow connections to the bus but not sure.  Anyone know?

Thanks,
