3.3 Indicators
Liquid Crystal Display (LCD):
The LCD display on the front panel of the power supply serves as the main
visual communications device so the user can view a number of operational conditions in the power supply.
Four membrane keys 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.
LEDs:
Six green light emitting diodes (LEDs) on the central area of the front panel provide visual indication
of power supply operational status. The operation of the LEDs are as follows:
