DESCRIPTION
The ON/OFF key may be used to control the state of the output
relay. The active state is indicated by the Output LED. If the
output relays are open (LED is off), the output is floating.
The PHASE key has no function and is a don't care.
The SET key selects the PROGRAM setting screen. While this
screen is displayed, the rotary knob can be used to change
either voltage or frequency. Additional output settings such as
current limit can be reached by using the down  cursor key. If
the PROGRAM screen is already displayed, the SET key puts
the unit in SET mode. For test options such as –704 or –160,
the SET key can be used to skip to the next test in a test
sequence during test execution.
The MEAS key selects the measurement screen. There are no
user changeable fields in the measurement screen. The rotary
knob is active while the measurement screen is displayed.
Additional measurement data can be displayed by using the up
 and down  cursor keys.
The top-level menu is accessed by pressing the MENU key.
Refer to section 4.2 for details on available menus. If a menu
screen is already displayed, the MENU key will advance to the
next menu.
The BACK key may be used to back up to the previous menu
level or previously selected screen. It can also be used as a
backspace key to delete the last digit entered.
For tests options such as the –160 and –704 options, the BACK
key can be used to abort a test in progress.
If the unit is in remote mode, (Remote LED is lit), the front
panel of the power source is disabled. The BACK button
doubles as a GOTO LOCAL button (LOCAL) while the unit is in
remote state. This allows the user to regain control of the front
panel. This LOCAL button can be disabled by sending a Local
Lockout bus command. This prevents unauthorized changes of
settings in ATE applications.
