Suffix None
*WAI
This command instructs the electronic load not to process any further commands until all pending
operations are completed. Pending operations are complete when:
Ϯ All commands sent before *WAI have been executed. This includes overlapped
commands. Most commands are sequential and are completed before the next
command is executed. Overlapped commands are executed in parallel with other
commands. Commands that affect input voltage or state, relays, and trigger actions
are overlapped with subsequent commands sent to the electronic load. The *WAI
command prevents subsequent commands from being executed before any
overlapped commands have been completed.
Ϯ All triggered actions are completed and the trigger system returns to the Idle state.
Command Syntax *WAI
Parameters None
