5. Force Motor Disassembly and Reassembly
This chapter describes the procedures and notes for the flexure assembly replacement,
bobbin cleaning, and adjustment after reassembling the force motor.
Notes: The disassembly and reassembly should take place in a dust free environment.
Adjustments and confirmations are needed after reassembly for linearity,
repeatability, creep, hysteresis and corner load error.
Temperature adjustment is also needed since the balance is affected by
tightening torque or stress. If you do not have the proper facilities to do the
temperature adjustment, do not attempt to adjust the temperature feature.
