S #215: Return distance (e) after the second contact
This macro variable specifies the distance (measured in mm)
through which the prove is to return after it touches the
measurement face the second time.
NOTE
An alarm is issued if the setting of any of the above macro
variables is 0.

This cycle uses a ring gage to measure probe compensation data and sets
measurement results in macro variables. The measurement cycle
references these macro variables for measurement. The calibration cycle
always involves two measurement sessions. The first measurement
session verifies the position of measurement, and the second
measurement session makes an accurate measurement at the verified
measurement position.
NOTE
Before executing this cycle, place a ring gage on the table,
and move the probe near to (right above) the ring gage.
The distance from the gage face on the tapered section of the spindle to
the stylus tip is measured by generating a G code program in the following
format:
