B. CALCULATIONS
This appendix contains the calculations used in calibrations and in reports available in the DVVA
II 4000 program.
Calibration
The force as a function of load cell voltage is found by a two-point linear calibration. One point
(F
1
, V
1
) is measured with no applied force, so F
1
= 0. The other (F
2
, V
2
) is measured with an
applied force.
The piston height as a function of linear transducer voltage is also found by a two-point linear cal-
ibration. One point (h
1
, V
1
) is measured with an empty chamber, so h
1
= 0. The other (h
2
, V
2
) is
measured with a reference standard of known height (h
2
) in the sample chamber.
