    I am testing using 2-wire mode but I have 2 units that will not adjust at this range.  I am starting to think I have 2 units that both have operational errors at this range.  All other parameters are adjusting correctly per the procedure.

    There is something missing in the adjustment manual for the 4-wire 100 MΩ resistance range.  The verification procedure has this range verified using a 4-wire setup but when sending the SCPI codes to adjust the range I keep getting error 702.  Also, the adjustment procedure has you put the instrument in RES mode instead of FRES mode for a 4-wire adjustment.  There is a type-o or omission somewhere and I have tried every combination of wire modes and actual resistance readings from the Fluke 5720A that I can think of.  Any ideas?
