DXC100A Differential Probe Pair

When the +probe has been properly adjusted it should be used as a reference.
CMRR adjustments made to the probe in the future should be done to the –
probe.
At this point, do not change any of the +Input X10 or +Input X100 Adjustments,
as doing so may require repeating the entire probe calibration procedure.
