OPERATING INSTRUCTIONS
3.1 CONTROLS AND INDICATORS
Front panel controls and indicators for the 3300 Series are identified in Figure 3-1 with index
numbers keyed to Table 3-1. Table 3-1 provides a description of all operator controls and
indicators.
3.1.1 Local
Operation
Units are shipped from the factory configured for local voltage/current control and local voltage
sensing. This configuration is used for applications where the IR drop of the load wires is
insufficient to degrade performance at the load. Prior to turning the unit on, rotate the voltage
and current potentiometers fully counterclockwise (minimum output). Then switch the power to
the ON position and adjust the voltage and current to the desired output.
