In the same position as you having just got my two panel Avo tester last week.
I think the document you mean is EMER which you can find here:

I may be wrong though I do recall seeing a document with VMARS on it but can not locate it. Because I am looking for it.
I have yet to get the actual tester out of the case, currently looking at the socket panel.
