"The best place for the probe is between the UTH and the glass. You didn't cover the probe itself when you taped it on did you?"
No only the Chord. But wont covering the probe-head with UTH be just as bad? hehe.
The probe chord is thick and UTH not that flexible, so if the probe is between glass and UTH, wont there be alot of gap/UTH not attached to glass? hm..
