3.8 Triggering function
Triggering function is necessary to operate dynamic pulse output and list output.
There are five triggering methods to trigger the tested instrument. Optional
triggering sources of triggering function of electronic load comprise:
 Key ([Trigger] key) trigger: when key trigger is valid, press [Shift]
+ .(Trigger) key and the load will trigger an operation.
 External trigger signal (TTL): TRIG on the rear board is the triggering
input terminal. When external trigger signal method is effective, after applying a
low pulse (> 10 us), the load will trigger an operation.
 Bus trigger: when the bus trigger is valid, after the load receives a trigger
command (GET or * TRG) from GPIB port, the load will trigger an operation.
 Timing trigger: when the timing trigger is valid, the load will automatically
trigger an operation at intervals.
 Trigger holding: when trigger holding is valid, only when the load receives
trigger command (TRIG:IMM), the load will trigger an operation.
Select the triggering sources as follows:
Operation steps
