To test reverb time you'd put the microphone and speaker at more or less opposite ends of the room. Everest suggests pointing the loudspeaker into a corner, and putting the measuring microphone about 2/3 of the way across the room on a mic stand.
Again, it is absolutely critical that whatever placements you use must be identical for all tests. If anything differs by even one inch, what is measured may change just from the placement difference.

Understood. I'll be taking pictures and posting them when I'm about to proceed.
