If you really want a calibration device, it's not that hard
to set up a spoke with a given weight hanging vertically
from the free end. For our less than mission critical non
NASA purposes, it works well enough.
I almost never recalibrate my own park tensiometer, because
as many have said here, I'm mostly interested in consitancy
of spoke tension in relationship to each other, and I pull everything
up into about the same range as Mr. Bunny ( I also use mostly
straight 14g spokes because they are easy to work with and
cheaper than the DB ones.) Pretty sure I could do so if I wanted
to though.
I actually find the thing a lot more useful for truing and retensioning
a wheel that comes to me history unknown and requiring some
tweaking. The ability to quickly run the whole wheel and see what's
high, what's low, and where they sit in relation to each other....
with a simple analog readout.....just sets my heart aflutter.
