6.2  KEYPAD OPERATION AND 
 DESCRIPTION
The keypad has 25 keys arranged into 4 groups.
 The rst group contains 8 keys in the bottom 
right hand corner of the keypad 
 
The First Group of Keys
GO  The GO button is used to start a test 
  from the machine console and is 
  operable from the “Pre-Test” display. 
STOP  The STOP key is used to stop a test 
  that is being performed from the 
  machine console, e.g., if the machine 
  does not stop automatically or the 
  user requires to abort the test.  This  
  is not an Emergency Stop Button.   
  The Emergency Stop Button 
  (Mushroom) is located on the left 
  of machine base and can be used to 
  stop the machine in an emergency 
 situation.
JOG     UP and DOWN   These two keys 
  allow the crosshead to be moved 
  slowly into position when loading and 
  removing samples.  They are 
  available when a test is not being 
  performed and only operate whilst 
  pressed.  The crosshead will run at a 
  user pre-set jog speed (a set-up 
 option).
FAST JOG UP and DOWN  These two keys 
  allow the crosshead to be moved at 
  a fast speed and therefore it is 
  essential to ensure there are no 
  obstructions.  These keys should only  
  be used for moving large distances 
  and not for nal adjustment when 
  the grips are close together.  They 
  are available when a test is not being 
   performed and only operate whilst 
  pressed.  
ZERO      Pressing this key sets the load and 
  extension values to zero.  This is 
  normally carried out at the start of 
  a test but can be used at any time 
  when not performing a test.  If Auto 
  Zero was selected in the set-up 
  routine the system will automatically 
  zero when  GO  is pressed. 
RETURN  Pressing this key returns the  
  crosshead to the position where the 
  zero button was last pressed.  The 
  crosshead will move at maximum 
  speed.  The return button is available 
  when a test is not being performed.
NOTE:  The STOP key is not to 
be used for EMERGENCY STOP 
conditions.  The Emergency Stop 
key is located on the left-side of the 
machine base.
