I'm using PXI-4071 DMM and PXI-2503 multiplexer to scan 10 resistors (1000-4000 Ohm) in 4-wire mode. DMM and the multiplexer are connected by standard cable (4 bananas to Analog Bus Connector on TB-2605). In Test Panels of MAX I can measure all resistors correctly by connecting com0 to ab0 and by switching channels 0 - 9 to com0, but I cannot write a correct scan list for a VI that would allow me to get correct measurements. I tryed com0->ab0 && ch0:9->com0 which should work accourding to my understanding of the manual, but it doesn't work. Can anyone advise me the correct scan list?
By the way I also have wires connected to com0 terminals in TB-2605 block and when I connect these wires to DMM instead of a standard connector VI works with the following scan list ch0:9->com0.
