Units of measurement and measurement variables for the calculation

INCH or METRIC unit of measurement
The following input and output variables are evaluated with inch or metric units of
measurement:
$AA_MEAS_POINT1[axis]
$AA_MEAS_POINT2[axis]
$AA_MEAS_POINT3[axis]
$AA_MEAS_POINT4[axis]
$AA_MEAS_SETPOINT[axis]
$AC_MEAS_DIAMETER
$AC_MEAS_TOOL_LENGTH
$AC_MEAS_RESULTS[n]
The system of units in which the input and output values can be read or written can be set
via the input variable.
INT $AC_MEAS_SCALEUNIT
0: Unit of measurement with reference to
1: Unit of measurement corresponds to
The value 1 is always treated as the standard setting if the variable is not written.
Example:
The basic system is metric:
G70
$AC_MEAS_POINT1[x] = $AA_IW[x]
$AC_MEAS_POINT1[x] = 10
G71
$AC_MEAS_POINT1[x] = $AA_IW[x]
$AC_MEAS_POINT1[x] = 10
G700
$AC_MEAS_POINT1[x] = $AA_IW[x]
$AC_MEAS_POINT1[x] = 10
G710
$AC_MEAS_POINT1[x] = $AA_IW[x]
$AC_MEAS_POINT1[x] = 10
