2.1.1.1 Load Measurement Indicators (L) There are two indicators that display the load measurement from the attached load cell sensor. The current load measurement is displayed numerically next to the L symbol with its associated units or measure.
2.1.1.2 Crosshead Distance Indicator (D) The D symbol is used to display the crosshead distance traveled. If the test system is in Height mode, the D is replaced by H to represent the height of the crosshead from the established datum. The crosshead distance is the amount of crosshead movement from the start of the test.
NOTE Press the L symbol to zero/tare the load cell sensor.
NOTE Press the D or H symbol to zero/tare the distance or height value.

Additionally, the load bargraph displays the direction of load (tensile = above the center line and compression = below the center line). The load bargraph is intended to provide the user with an indication of the load being measured versus the full scale capacity of the load cell sensor being used. Color indication is used to represent the measured load versus the load sensor’s capacity as follows:
Current Height Measured by the encoder from the datum established by the user
Press to zero the height measurement

The sensor is operating within its normal range 0 to 80% of full scale capacity. The sensor is operating in its caution range 81 to 95% of full scale capacity. The sensor is operating in its high range 96% and above. Be alert of the measured load overloading and potentially damaging the sensor. Load Sensor Status Indication
