Local/Analog
Pin 8 can be used to select the control mode (Local or Analog) of the power
supply’s output. When the input command for this pin is at High level (or
open), the control mode will be Local. When input command for this pin is
at Low level (or connected to common GND), the control mode will be
Analog. In analog mode, setting and measurement resolution for voltage
and current will be less than local mode. See the below figures as an
example.
