For example, the user may enable the current source output (LAS:OUT 1),
enable an SRQ on Operation Complete (set *ESE 1 and *SRE 5), and have an
SRQ handling routine in the user's software, that reads a new measurement after
the output on state has been reached. This allows the use of the operation
complete features of the LDX-32420, without the need for program looping or
polling that can tie up the communication bus. Operation Complete on the
LDX-32420 is defined as:

use SRQ generated interrupts in your program. See your GPIB manual for
time-out configuration or SRQ programming setup.
The *OPC, *OPC? and *WAI commands should not be used inside a calibration routine.
