The operating mode of each output is determined by the output’s programmed settings,
operating point, and load condition. Because these conditions may change during series
operation, the front panel status indicator will reflect these changes. This is normal.
Momentary status changes are also normal.
Effect on Specifications
Specifications for outputs operating in series can be obtained from the specifications for single
outputs. Most specifications are expressed as a constant or a percentage (or ppm) plus a constant. For
series operation, the percentage portion remains unchanged while constant portions or any constants
are changed as indicated.
Voltage: All series specifications referring to voltage are twice the single output specification except
for programming resolution, which is the same as for a single output.
Current: All series specifications referring to current are the same as for a single output except for CC
load effect, CC load cross regulation, CC source effect, and CC short term drift. These are twice the
current programming accuracy (including the percentage portion) at all operating points.
Load Transient Recovery Time: Load transient specifications are typically twice the single output.
