4.9.2.3.3.Reference Resistor
This is used to record the value of the reference resistor used to calibrate the 6530.
It is critical that it be entered prior to calibration of the 6530.
A separate value for variance, standard deviation and sample size is used for
2700 pF, 270 pF, 27 pF, 1.0 V threshold and 0.1 V threshold.
Variance is the difference between the maximum and minimum reading in ppm.
This is used to ensure that the reading has stabilized before calculating the
calibration coefficient.
