Sensing the Output Level
Although the front and rear output terminals simultaneously supply
power, the power supply senses the voltage level internally from
either the front or rear terminals. Use the SENSE selector located on
the rear panel to select the appropriate sense input. See Figure 15.
As the length of the output leads or the amount of output current
increases, the amount of voltage drop across the output leads also
increases. In this case, the internal sense connection does not
accurately measure the voltage across the load. To compensate for
