It's very doubtful that his meter is 10m, because he has an electrician's (clamp) meter, and not a full function DVM, this has been brought up several times before by quite a few, including myself that he invest in a better one that has a dedicated 10a scale, and was made for the electronics field rather than an electrician, because it is very likely it's giving inaccurate readings in some cases.
He has this.

Again, a better meter is suggested before believing any voltage readings, one that is known to be 10m, as the one on hand may be loading the circuit down.
