Hey there Roy. Getting a clear reading on the 3rd of E6 can be difficult for sure.
You'll find its about 25 to 30 cents high. But if you half mute with the back of
your fingernail, you can get the 3rd harmonic to sound pretty loudly and and ETD
will pick that up just dandy.

Yes, this is what I do to get E6 tuned, but then I switch to the 3rd partial of E6
to get a reference point there.
I find tho that I like to tune the area from A#4 to E6 by referencing what Tunelab
has calculated for the 3rd partials  D#4 to  A4, and then just continue the process
up.

Tune Lab is great for fooling around like this when you get the time. Try tuning in
this fashion once or twice to see what you come up with. It consumes a bit more time
then otherwise, but its interesting.
