Description
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.
Specifies the Poisson ratio of the strain gage. Poisson ratio is defined as the negative ratio of the strain
in the transverse direction to the strain in the longitudinal direction.
The Poisson Ratio softkey will only be available when Poisson is specified as
the type in the Sense menu.
Use the knob or the front panel arrow keys to specify the fixed excitation voltage applied to the bridge
by an external voltage source. This value will be used to convert strain bridge measurements on the
selected channel.
