Measuring AC milivolts

Using the Adam5000 with Adam-5017, what is the best way to measure AC milivolts?

Hi,

Sorry that we don't have millivolt AC input module, that could integrate with directly with ADAM-5000. The only AC input module we have which is a signal conditioning that convert AC to DC voltage is ADAM-3112.

Assume you config ADM-5017 as +/-5V range, that it will be able to detect as small as 0.152mVDC.
So scale back for the ADAM-3112 (Input: 0-120VAC, output: 0-5VDC) it roughly give you approximately 4mVAC. But the ADAM-3112 also has ripple voltage of <120mVp-p so it depends on your application if these spec is acceptable.

Thanks.

Looked at the ADAM-3112, I am using 12VDC, so this will not work for me. Looking at building something.

Thanks.
