The wall mounting holes are fine for ground when reading any secondary supply voltage from the power board, but you are measuring DC, not AC.

Even so, those supplies are well bypassed and I'm surprised your meter is giving you those readings on the AC scale. What kind of meter is it?

If your meter has a min/max feature, preset the range for higher voltage and record the max voltage for the VS and VA.

If it doesn't have the min/max, just read the highest value you see before it shuts down.
