Indicators
:
Liquid Crystal Display (LCD):
The LCD display on the front panel of the power supply serves as the main visual
communication device so the user can view a number of operational conditions of the power supply at any time
desired. Four buttons associated with the LCD display provide a means for the user to navigate the individual screens.
Further description of the menu tree may be found in the
Startup and Operation
section of this manual.
