5.8.4 Parallel Operation(one master and multi-slaves)
"One master and multiple slaves" means that there is only one instrument with
operating panel (namely, the master) in the parallel system, and the other
instruments have no operating panels (namely, the slaves). In the "one master
and multiple slaves" system, you only need to operate the master's front panel.
This section uses three instruments as an example to introduce the steps for
parallel connection with one master and two slaves. The type and assembly
method for parallel connection of other quantities of instruments are the same.

corresponding specifications for the AC input parameters of a single
instrument.
