Expressed by three-digit alphanumerics. The unit is ohm ( ). The
first and second figures are significant digits, and the third figure
expresses the number of zeros which follow the two figures. If
there is a decimal point, it is expressed by the capital letter "R." In
this case, all figures are significant digits.
