Details
Contact check measurement calibration does not require range information.
Typically, points one and two are near 0 Ω and 50 Ω, respectively.
All four measurements (cp1Measured, cp1Reference, cp2Measured, and cp2Reference) must
be made with the calibration set that is active. If not, corruption of the calibration constants may
result.
