9.0  SETTING UP A NEW TEST
9.1  PRE-DEFINED TEST SETUPS 
The LS is supplied with three pre-dened test setups and one for new test setups, these are:
LIMIT_TEST  A test which is carried out to a limit.  The limits are dened in mm or inches, 
    % elongation (after setting gauge length), Newtons, Kg force, lbs force, Mega 
    Pascal’s Mpa (have entered the sample dimensions), Kg force per mm² and lb 
    force per inch²
CYCLE_TEST  A cycle is from home to a limit (as set out above) and back to home.  If when 
    the test starts the crosshead is not at the home position, it will move to the 
    home position rst before going to the limit position.  The machine can be set 
    to perform up to 10000 cycles per test. 
BREAK_TEST  A Break Test will either, stop at a limit as described above or when a break is 
    detected.  There are 2 types of break detector.  A % break detector which 
    detects when the load has dropped to 50% of the maximum peak load 
    detected and sharp break detector.  The sharp break detector operates when 
    there has been a sharp change in load or direction between one load reading 
    and the next.
NEW_TEST  Is a user dened test rather than one of the default settings which are detailed 
    on the next page.
