Master/Slave Operation
The SERIES and PARA controls on the front panel allow you to
internally connect Output 1 and Output 2 in series or parallel. When
you do this, Output 2 (the master output) sets Output 1 (the slave
output) to the same level as the Output 2 setting. These modes of
operation are also called series tracking and parallel tracking.
Output 3 is always independent. You can connect Output 3 in series
or parallel with the other outputs by using external connections only.
Table 1 shows the maximum output available for the power supplies
in SERIES and PARA operation

Series Tracking.
Select SERIES to internally connect Output 1 and
Output 2 in series. Output 2 is the master.

Use the Output 2 settings to control the power to the load. The
Output 2 voltage setting should be one half of the total output
voltage desired. (The voltage across Output 1 and Output 2 in series
is twice that of Output 2.) The current setting for Output 2 controls
the maximum current available to the load. See Figure 12.
