To set up a conditional command:
1 Insert an If…then command at the appropriate place in the cycle definition.
2 Specify the condition. This is defined as the outcome of a comparison
between a report point value (absolute response, relative response or slope)
and a constant or another report point value with an added or subtracted
constant value. Only report points that have already been set in the cycle
definition may be used in the condition.
Check Use additional condition to combine two conditions, using either
AND (both conditions must be fulfilled) or OR (fulfillment of one condition is
sufficient) as a logical operator.
The available comparison conditions are Greater than and Less than . The
conditions do not include Equal to since exact equality is an unpredictable
condition in view of noise in the SPR response. To construct an equality
condition, combine one
Greater than and one Less than condition so that
a window of tolerance is created. For example, the combined condition A
greater than B-1 AND A less than B+1 is equivalent to A equals B with a
tolerance of
±
1.
3 Choose the actions to be taken when the condition is met and when it is not
met. You may choose to execute a command sequence, terminate the
cycle or the method, or introduce a stabilization period.
If you choose a command sequence for either the True or False outcome,
click on the appropriate branch of the command ( Then or Else respectively)
and insert the commands you wish to be executed. If you leave the branch
empty, the cycle will simply continue with the next command following the
If…then construction.
You can use the Move up and Move down buttons to rearrange the order
of commands within a branch, but you cannot move commands outside
the branch in which they are placed.
