Sets bit 0 (OPC for "Operation Complete") in the Event Status Register to 1 when all

After sending an OUT command, check if the output has settled by sending *OPC. As
soon as the output has settled, a pending *OPC command sets bit 0 (OPC for "Operation
Complete") in the Event Status Register to 1. The command to read the ESR is *ESR?.
Sequential command.
Causes program execution to pause until all operations are complete; returns a 1 upon
completion of these operations. (See also *WAI.)
None
(Integer) "1" after all operations are complete.
If an OUT command had been sent, check if the output has settled by sending *OPC or
*OPC?. As soon as the OUT command has completed (output settled), a pending *OPC
command places a "1" in the output buffer to be read by the controller.
Overlapped command, ignored if not in remote.
Activates the Calibrator output if in standby. OPER is inhibited for outputs 22V and over,
if there are faults in the fault queue (see "Fault Queue").
