I use the large knob on the front, provided for that purpose. :)
The "scan" function isn't really very dependable, there are always lots of
emitters around that need to be ignored. With a little practise, and a
convenient on/off switch, the parts that come from my product are easy to
I also built a screen box, which lets me make more deterministic measurements.
It's simply a box, of double sided PCB material, with all seams soldered.
The lid has inner and outer overlaps, and finger stock to assure solid
With all that being done, you'd expect easy measurements, but nothing
worked in a repeatable manner until I lined the inside with MOSfoam. Turns
out (and you knew this) that putting an emitter inside a tight shielded box
is like putting light in a box of mirrors.
I put mosfoam slabs now in my computer cases, inside ziplock bags, cuts way
down on the amount of hash in the office. I've also used them in
transmitters and receivers.

Bi-directional read of UPC-A, UPC-E, EAN-8, EAN-13, JAN, and Bookland, with
