Here's a picture of the calibration device I use with the Flite Tork
meters.The hook is located to give 1 in-oz of torque with a 10g weight.
I've used it to check a spring meter by hooking the meter to the
calibrator shaft and then rotating the meter until the calibrator shaft
is horizontal.

In order to get an accurate reading when calibrating a Flite Tork meter
I rubber band the meter and the calibrator together, engage the hook on
the meter with the slot in the calibrator, zero the scale and then add
the 10g weight to the hook on the calibrator arm. There is obviously a
lot of points of friction in this device so I tap on the table and/or
one of the two pieces until I get a steady reading. I look for a final
reading of between .98 and 1.02 on the meter (+/- 2% error at 1 in-oz).
Adjusting the previous meters by bending the pressure arm was a
nightmare. I've designed a new pressure arm that is much easier to
adjust and eliminates some soldering operations. Here's a picture of an
early version:
