Adjust the output of DC calibration generator until it precisely
overlaps the top (upper) level of the stored probe compensation
signal. (This value will be near 500 mV.)
Record the setting of the DC generator.
Adjust the output of DC calibration generator until it precisely
overlaps the base (lower) level of the stored probe compensation
signal. (This value will be near zero volts.)
Record the setting of the DC generator.

e.
Check against limits:
Subtract the value just obtained (base level) from that obtained
previously (top level).
CHECK that the difference obtained is within 495 mV to 505 mV,
inclusive.
