AC measurements using NI-9242

[JohnatanBravo]

Hi all,

I have an NI9242 voltage input module, wired as per the below diagram:

When I go to NIMAX and perform some measurements in the Test Panels, I get the following readings (the final reading jumps randomly to anywhere on the waveform):

I get same results when measuring it in my VI:

What additional step would I need to perform to get values in ranges of 230V AC? (Same as a handheld DMM would show)

I made the following changes, now I am getting a proper AC reading:
