I just came here to ask the same! For reference, my Fluke 101 reads:
44: 5M (25M if I move the ground lead to the input buss wire)
45: 4.5M
47: 8M
I did get a lot of readings between 10-30M on ones with a * (no issue), but these threw me.
Bottlehead crew, your answer makes sense and glad to validate.
Thanks!
