tion CLEAR button resets the overvoltage and overcurrent protection if it has tripped (voltage and current
are reset to the programmed values in effect when protection tripped). The Memory button opens the Pro-
gram Memories
window that allows the active values for output current and voltage, and programmed set-
tings for overvoltage and overcurrent protection to be stored in one of the 40 available memory locations,
or be recalled from a previously stored location. The Trigger button opens the Trigger window which
allows trigger voltage and current values to be set; the Trigger button within the Trigger window causes
the power supply output to be programmed to the settings of trigger voltage and current. The Calibrate
button is used to recalibrate the unit (see Section 4 of the Technical Manual). The Reset button resets the
unit to the power on defaults: output voltage and current set to zero, overvoltage and overcurrent set to
approximately 10% above rated maximum.

The ABOUT button displays the model, serial number and firmware version number. The Limit button
opens the Limits window that reveals the Voltage and Current Limit settings. The Program button opens
two windows used to control local programming. The Edit Program Memory window is used to view or
change any of the six stored parameters for the memory location selected by the Memory window. The V >
OV
and C > OC indicators light (red) if the Edit Program values for voltage or current exceed the Edit Pro-
gram
values for Overvoltage or Overcurrent. The Program Window is used to execute the local program
established by the Edit Program Window. The Step button executes one memory location at a time, start-
ing at the Start Address; the Step Mode indicator lights after the first step is executed. As each step is
executed, the corresponding values for each parameter are displayed in the Edit Program Memory win-
dow. The Run button causes the program to be executed starting at the location in the Start Address dis-
play window; the Running indicator lights (green) while the program is running. The Clear button stops a
program that is running.

The Keypad button either enables (UNLOCK) or disables (LOCK) the local keypad of the selected ABC
power supply. The Display button opens the Display Change window which allows adjustment of the local
LCD contrast, and selection of Normal/Text mode for the LCD. In Normal mode, the bottom line of the local
LCD displays output voltage and current. In Text mode, the text typed in the Display Message window is
displayed on the bottom line of the LCD. The QUIT button is used to exit the sample VISA application.

WARNING:

Once the program is started, actual values of output current and volt-

age are displayed. If you exit the program while the power supply is still

on, the programmed settings in effect at that time are maintained after

exiting the program.
