4.1.1 QUICK OVERVIEW (cont)
SELECTING OPERATING MODES
On first turn-on the system will operate using a set of default parameters stored in memory. The display
will be the V/I METER display. This is the default - and most frequently used - display. It shows all basic
operating parameters, and in the lower left portion shows the operating mode. All operating modes can
be accessed from the V/I METER display. If the V/I METER display is not active, pressing
CLEAR a few
times will always return to the V/I METER display.
MANUAL OPERATION (para. 4.3) - is available by pressing Va, Vb, Vc or F for voltage or
frequency adjustments. An LED will light above a pressed key to indicate an active
selection. The selected parameter can then be changed by typing a new value and
pressing
EXECUTE or holding one of the SLEW keys (
︿
or
﹀
).
PROGRAM OPERATION (para. 4.4) -requires pressing PROGRAM, select a program number
(1-99) and press ENTER to display the values stored in that program. Pressing
EXECUTE will then cause the UPC to use those values. If a transient as been stored in
the active program, pressing TRANS will activate the transient.
PROGRAM EDIT (para. 4.5) – is accessed by pressing PROGRAM, select a program number
(1-99) and press ENTER to display the values stored in that program. Press EDIT to
allow changes to the values stored in that program, ENTER to move the cursor through
the screen, and STORE to save the values.
SETUP MODE (para. 4.6) Pressing the fn key presents the menu list of SETUP features. It is
used to copy and delete programs, erase memory, copy and edit waveforms, set meter
sense points, toggle CSC on or off, set Programmable Output Impedance (option), set
Output range (for power sources that support it), transition time, min and max
frequency, min and max voltage. Calibration for metering may also be performed.
Status is given for system information such as firmware version, GPIB device address
or RS-232 serial interface parameters, transformer ratio, amps to volts ratio, number of
Power Source amplifiers and current transformer location
NOTE: The five keys in the lower right portion of the keyboard (highlighted with a different color) are
executive keys. Every attempt has been made to ensure that:
•
In order to change power applied to the load one of these keys must be pressed.
•
Whenever one of these keys is pressed, power to the load may be changed.
This operational feature has been designed to help keep the user from accidentally pressing the
wrong key and unintentionally changing power to the load.
Remember! When you press a BLACK key something will probably happen to change output
power.
