AI Current RMS

[ASTDan]

Hello,

I found the AI Current RMS Virtual Channel setup (see attached).

I would like to use this with the NI 9227 CDAQ module.

I get an error AI Current RMS is not compatible with the device.

What devices are the AI Current RMS Compatible with?

Thanks

Hi ASTDan,

The AI Current RMS create channel VI was added to support the DMM channel on the NI ELVIS II/II+. With the NI 9227, you'll have to calculate RMS values in software. I don't currently have it installed, but it sounds like the Electrical Power Measurement palette might help.
