ViStatus = niDMM_ConfigureOffsetCompOhms(ViSession Instrument_Handle, ViInt32 Offset_Comp_Ohms)
Purpose
For NI 4080/4081/4082 and NI 4070/4071/4072, allows the DMM to compensate for voltage offsets in resistance measurements. When Offset_Comp_Ohms is enabled, the DMM measures the resistance twice (once with the current source on and again with it turned off). Any voltage offset present in both measurements is cancelled out. Offset_Comp_Ohms is useful when measuring resistance values less than 10 KΩ.
