Model 2657A High Power System SourceMeter® Instrument Reference Manual  Section 7: TSP command reference

Details 
The SMU will automatically clear all the event detectors when the smuX.trigger.initiate() function is 
executed. This function should be called after the sweep is initiated. 
A common example of when this function can be used is when you want the SMU to immediately perform an 
action the first time through the trigger model even if a programmed trigger event does not occur.  
This function can also be used to start actions on the SMU in case of a missed trigger event. 
 
Example 
 
smua.trigger.arm.set() 
 
Sets the arm event detector to the 
detected state for SMU channel A.
