I am trying to set the 4071 and 4081 DMM's input resistance via the DMM property node. I have gathered from other posts that the range of possible settings (1M, 10M, >10G) is limited by a combo of Auto Range, Range, and (possibly) Auto Zero settings. I am unable to get the device to enter 1M mode. Any thoughts on what settings are required to allow the devices to enter 1M input resistance mode?
