Appendix A - Compensation Types & Parameters
The table below shows the supported methods of calculating the Volume Correction Factor (VCF). The method is
independently selectable for each product in Product Calibration. The table below shows the valid temperature
ranges for each table. The hold temperature, T
hold
, is the temperature that VCF is held at for temperatures < T
hold
and
> T
min
. This is done to allow compensation in very cold environments where further extrapolation of equations is not
allowed.
