Hellow. There is any troubles with PXI-4110 current range programming. My algorythm:
1. Init dev
2. property node: active channel, output enable true, output function DC volt
3. property node: active channel, voltage level (variable), current limit avtorange on
4. Measure multiple, reading result (current, current range immediate value)
In attachment - my version of algorythm realisation.
Value o current limit range still 1. Required voltage 3.3V.
Would you send me example for current limit range changing?
Thank you!

Hi Gorge-
To set the current or voltage ranges, you must use the VIs found on the DC Voltage palette. They can be found on the block diagram by navigating to Measurement I/O»NI DCPower»Source»DC Voltage. There are four VIs in there that configure the voltage and current range and limit. For an example of how to use these, you can look in the LabVIEW Example Finder. In LabVIEW, click on Help»Find Examples. Once the example finder opens, navigate to Hardware Input and Output»Modular Instruments»NI DCPower»NI-DCPower Source DC Current.vi. While this VI sources current and probably doesn't do what you want, it demonstrates how to use the Current/Voltage Range/Limit VIs. These will allow you to set the voltage or current range of your device.
I hope this helps. Best of luck with your application!

Thanks, i've found solution, there was nesessary to set both current range and current limit in same state (0.02 or 1).
