DMM Over range Warning but IsOverRange false

[NotSureJoe]

Hi,

the function niDMM_Fetch sporadically returns the warning code 1073356801 (0x3FFA2001 "Over range.") with a measurement of 105 to 140 MOhm when using Auto Range. However the subsequent check with niDMM_IsOverRange returns VI_FALSE. As I understood 

Can anyone explain this or is this a bug?

Thanks in advance and best regards,

Michael

So, for all those who are looking for the answer, NI R&D has confirmed this behavior as a bug (no. 2035720).

It occurs every time a resistance above 100 MOhm is measured with the PXI-4082 and Autorange enabled.

Best regards,

Michael
