2.1.3.3 Test Mode Indicator Your L3 system has two test modes: • Normal Mode • Height Mode When in normal operating mode, the zero or datum position is established when you specify the Home position using the SET HOME command. When in normal mode, the D symbol is used to display the distance the crosshead is from the established Home position. When in height operating mode, the zero or datum position is established using an automatic pre-test routine. The user must first place the system in Height mode. This can be done using the Pre Test step, or by selecting the Test Mode indicator and selecting the height mode. When in height mode, the H symbol in the Controller view represents the current height from the datum position. NOTE Height Mode may not be used when in stress/strain testing.
2.1.3.4 Joy Stick Speed Indicator The joy stick speed indicator shows whether the joy stick is set to SLOW or NORMAL speed. Select the indicator to toggle between Slow and Normal speed. When shown in SLOW speed mode, depressing the Up/Down joy stick causes the crosshead to move at the slowest velocity. When shown in NORMAL speed mode, depressing the Up/Down joy stick causes the crosshead to move at a variable speed up to the maximum crosshead velocity you set in the SETTINGS/MOTION function. See User Guide 7 - Security and System Settings for details on how to set maximum velocity. CAUTION Do not attempt to change the speed while pressing down on the joy stick.
