7.6.3.5.2 Attribute 0x66/0x67, Revolution Numerator/Divisor
Together, these two parameters Number of Revolutions Numerator and
Number of Revolutions Divisor define the Number of revolutions before the
measuring system restarts at zero.
As decimal numbers are not always finite (as is e.g. 3.4), but they may have an infinite
number of digits after the decimal point (e.g. 3.43535355358774...) the number of
revolutions is entered as a fraction.
