1. Before attempting to verify parallel operation, perform the power-on test
2. Connect the outputs for parallel operation per the section, Parallel
3. Connect appropriate instrumentation for measuring the output voltage
4. Configure the modules into a parallel group with the following command,
5. Verify that the parallel group has been properly set up with the following

where [n1] is the master module of the group. Although the example is
for two modules, it could be extended to a greater number by listing
additional parameter slot numbers, [n].

command. SYST:GRO:CAT:PAR?. The response to the query is a listing
of the master module of the parallel group. For example, a group of
modules with a master in slot 3 and a slave in slot 7 would return the
parameter, 1003. The parameter, [1000+n1], is the sum of 1000 and
the slot number of the master module; the master module is the left-most
module of the parallel group.
converters, and program full scale voltage and current with the following
commands. The parameter, <fval>, is the full scale output voltage or
current of the particular model under test. The parameter, [1000+n1], is
the sum of 1000 and the slot number of the master module; the master
module is the left-most module of the parallel group. For example, if the
master module is located in slot 1, the parameter value would be 1001.
