Coupling
The Calibration Tools window allows you to check and adjust the coupling of the instrument
to the torque tube. See the instruction EU 12400 for details of the mechanical method that
must be performed. Coupling adjustment is normally performed in the workshop when the
instrument is assembled to the torque tube. 
The adjustment may be inspected using ValVue and a special weight. The displacer must be
removed and the instrument removed from service to perform the check.
To start the coupling calibration:
1. Change the mode to Setup.
2. Tighten the adjustment screw. (For a standard displacer (907 cm3, 1362 gr), hang 727.1 gr
on the torque arm. See the instruction for a special displacer.).
