One of the MAINTENANCE screens used is the Analog to Digital Voltage screen (see 3.3.2.1). This
screen shows raw data coming from antenna position sensors (potentiometers and resolvers).

Another MAINTENANCE screen that will be used is the Limits Maintenance screen ( see 3.3.2.5). This
screen shows the current sensed state of limit switches for all three axes.
AZIM CW:0 CCW:1 STOW:0 (0-OFF) LIMITS
ELEV UP:1 DN:1 STOW:1 (1- ON) ACTIVE

Before beginning axes calibration, the installer should become familiar with accessing these screens.
