L2 Plus Operating Fundamentals

2.1.1.3 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.

2.1.1.4 Load Cell Status Indicator The Load Cell Status Indicator shows the full scale load capacity of the connected load cell sensor. The load cell symbol changes color to Yellow or Red depending on the sensor’s measured load versus its full scale capacity. Selecting the Load Cell Status Indicator displays the sensor’s characteristics, including its Overload History. All Starrett load cell sensors are compliant with IEEE 1451.4 (TEDS). These sensors are “plug & play”, e.g. your Starrett system automatically recognizes the sensor and its characteristics and performance specifications.

Load Cell Status Indicator - Top right on all displays

Select the Load Cell Indicator to view the attached sensor’s identification and characteristics. Overload History is displayed. The current load cell sensor’s full scale capacity is shown beneath the Load Cell Indicator symbol.

Shows the current crosshead velocity

Shows the current step for this test (Step 2) including the Distance Limit target and the crosshead speed setting (S) for Step 2. Also shows the current step is a tensile (Pull) step going to a Distance target of 25.000mm

Load Cell Sensor Status View

NOTE Overloads may occur when the software is not controlling the test frame on which the load cell is installed. When this occurs, a record of the overload will display underneath the Overload History, but with a date which is not current. For example, the date stamp may have the year 1999. This means an overload occurred and was recorded by the load cell sensor, but not by the software since it was not controlling or communicating with the test frame.
