Crosshair X670E Extreme OSC_SENSE pin definitions

The Asus ROG Crosshair X670E Extreme motherboard comes with the True Voltician peripheral. It's supposed to be connected to the OSC_SENSE pins on the motherboard and it displays voltage information as "Channel 1", "Channel 2", and "Channel 3". There is no indication what any of it means. For the Intel board, on this site (https://skatterbencher.com/2021/11/04/alder-lake-overclocking-whats-new/), it's claimed that "the pins on the motherboard, from left to right, are for Vcore, VCCIN, and VccSA." However, that site lists absolutely no source. Since VccSA is specific to Intel, I don't think the same pin definitions apply for Asus's AMD motherboards.

I've scoured the internet and Asus's documentation for the definitions and come up with nothing. I've talked to Asus support and it was a total waste of time. They first linked me to the True Voltician documentation (thanks, obviously that's the first thing I looked at) and then told me "This HEADER can only be connected to our own oscilloscope small card, so it does not have an available pin definition."

Does anyone know what those channels/pins actually mean on the X670E motherboards?

i put up the walkthru in my word document guide here:

Thank you so much! That's very helpful. For reference for others, the document says Channel 1 is Vcore, Channel 2 is SOC, Channel 3 is CPU current.

It's a bit strange to measure current with a voltage reading... Judging by contemporaneous wattage measurements in Ryzen Master, I'm guessing every 10 mV is 1 A?
