I am maintaining some software that is doing a 2 wire resistance measurement of three transformers in parallel, looking for shorts. The lower limit of the three should be 17.14 ohms. I am testing this with a PXI chassis, and the PXI 4072 DMM. It is going through the 2532 (2 switches), and about 5 feet of cable to make the measurement. I have been asked to change the lower limit of this particular test, which is currently set at 20 ohms. I am trying to find out the lower resistance limit we should see in this. When I looked in the datasheet, it just shows <1ohm. Is there an average for it?
