Gage Factor - Gage factor is the ratio of the fractional change in resistance to the fractional change in
length (strain) along the axis of the gage. The larger the value, the more sensitive strain gage. Gage
factor is a dimensionless quantity. The typical value is approximately 2.
Gage Ohms - Gage resistance to be used to convert direct strain measurements on the selected chan-
nel.
