8. Ensure that the actual values of the output parameters are within
specifications of the programmed values.
9. Query the values of the output parameters with the following
commands:
MEAS[2000+n1]:VOLT?
MEAS[2000+n1]:CURR?
10. Ensure that the readback values of the output parameters are
within specifications of the actual values.
11. Turn off the output with the following command:
*RST[n]

1. Before attempting to verify series/parallel operation, perform the
power-on test of the individual modules per the section, Power-On
Check, and then the standalone operation test per section,
Standalone Configuration.
2. Connect the outputs for series/parallel operation per the section,
Series/Parallel Configuration. Ensure that the outputs and remote
sense are appropriately hardwired prior to issuing any of the
series/paralleling SCPI commands.
3. Connect appropriate instrumentation for measuring the output
voltage and current, as well as a load.
4. Configure the first set of modules into a parallel group with the
following command, where [n11[ is the first master module.
Although the example is for two modules, it could be extended to
a greater number by listing additional parameter slot numbers,
[n] .
SYST:GRO:DEF:PAR [n11],[n12]
5. Configure the second set modules into a parallel group with the
following command, where [n21] is the second master module.
Although the example is for two modules, it could be extended to
a greater number by listing additional parameter slot numbers,
[n]
.
SYST:GRO:DEF:PAR [n21],[n22]
6. Verify that the parallel group has been properly set up with the
following command. The response to the query is a listing of the
parallel group, the master module of the parallel group, and the
slave module of the parallel group. For example, two groups of
parallel modules, with the first group having a master in slot 3 and
a slave in slot 4, and the second group having a master in slot 5
and a slave in slot 6, would return the following parameters:
