Calibration increases accuracy of a measurement device by adjusting its output, or
the measurement of its output, to match independently verified quantities.
Adjusting sensor output directly is preferred, but not always possible or practical.
By adding FieldCal() or FieldCalStrain() instructions to the CR1000 CRBasic
program, measurements of a linear sensor can be adjusted by modifying the
programmed multiplier and offset applied to the measurement.
