If you do not define the measure block, it will compare measurements of a measure block that
precedes the branch delta block. For example, if you have a measure block, a wait block, another
measure block, another wait block, and then the branch delta block, the delta block compares the
measurements from the second measure block. If a preceding measure block does not exist, an error
occurs.
Example
trigger.model.setblock(5, trigger.BLOCK_BRANCH_DELTA, 0.35, 8, 3)
Configure trigger block 5 to branch to block 8 when the measurement difference from block 3 is less than 0.35.

trigger.model.setblock() —
trigger.BLOCK_BRANCH_LIMIT_CONSTANT
This function defines a trigger model block that goes to a specified block if a measurement meets preset criteria.

Usage
trigger.model.setblock( blockNumber , trigger.BLOCK_BRANCH_LIMIT_CONSTANT, limitType ,
limitA , limitB , branchToBlock )
trigger.model.setblock( blockNumber , trigger.BLOCK_BRANCH_LIMIT_CONSTANT, limitType ,
limitA , limitB , branchToBlock , measureBlock )
blockNumber The sequence of the block in the trigger model
limitType The type of limit, which can be one of the following types:

trigger.LIMIT_ABOVE

trigger.LIMIT_BELOW

trigger.LIMIT_INSIDE

trigger.LIMIT_OUTSIDE
limitA The lower limit that the measurement is tested against; if
limitType
is set to:

trigger.LIMIT_ABOVE
: This value is ignored

trigger.LIMIT_BELOW
: The measurement must be below this value

trigger.LIMIT_INSIDE
: The low limit that the measurement is compared
against

trigger.LIMIT_OUTSIDE
: The low limit that the measurement is compared
against
