Ben, Do you have the 4921 Current Shunt Adapter option for the 4920? I have not found any information on it other than what is listed in the 4920 user's handbook. It mentions the unit simulates the impedance of a 540B. The guide says that the instructions are included with the 4921. Do you happen to have a copy of that document?
The 4920 user's guide is on the KO4BB website.
