When I worked in a metrology lab we calibrated cable tensiometers that
are used to measure aircraft surface control cables, buy suspending
known weights to equate to 25, 50, 75, 95% of full scale, from a like
piece of cable approximately (if my memory serves me right) four feet
long. I would think that one could duplicate this procedure using EHS
and then Phyllistran and come up with some empirical data to verify if
in fact the Loos tensiometer readings are repeatable and are within the
manufacturers accuracies.
Good luck, Dick
