I am having trouble trying to Acquire multiple Channels which have multiple Custom Scales defined.Is there a way to define multiple Custom Scales within the same acquisition, I tried seperating them with a comma but this does not seem to be allowed.Furthermore the Min and Max from the Custom Scales vary as wellAny help is more than welcome: if (DAQmxCreateAIVoltageChan(thndLocal, // Task Handle "Dev4/ai0:3", // Channel List "", // name to Assign DAQmx_Val_Diff, -10, // Expected minimum 10, // Expected maximum// DAQmx_Val_Volts, // Units DAQmx_Val_FromCustomScale, "Top Torque Scale,Bottom Torque Scale,PS Voltage Output,PS Current Output") // Custom SCale < 0) { // <0 Error // =0 Success // >0 Warning

I guess my reason for asking is why do you need to create a task? Why not just create the virtual channels?

It would work the way you have it too, but you could just leave the first VI off of it
