2.1.1.3 Extensometer Indicator (E) The E symbol is used to display the sample elongation as measured by an external extensometer that is connected to the test frame. The elongation E, is always expressed as a percent value indicating the change in sample length from its original value prior to load being applied. NOTE Press the E symbol to zero/tare the elongation value.
2.1.1.4 Crosshead Velocity Indicator During a test run, the crosshead velocity is indicated. Velocity is displayed for the current step being performed. Velocity may change during a test if you have specified a different crosshead velocity for a step. When automatically returning to the Home position, the crosshead velocity is returned at the maximum crosshead speed. Maximum velocity is an option in the System Settings - Motion Setup. Velocity is displayed with the unit of measure equal to the units of measure for the Distance (D) or Height (H) indicator.
