Cycle the MENU button to Save To Memory and select a memory location by entering it

CONTROL SOURCE The control source for the
power supply is the location from which the output of
the power supply can be controlled. To select the
control source for the power supply, cycle to the Control Source function, and then use
the
bc keys to scroll through the eight programming modes. The four modes are listed
below.
KEYBOARD All control is from the keyboard.
REM ANALOG This mode allows an analog remote source connected to the power
supply at the input connector J1 on the rear panel to control the power supply. This
control mode enables the remote source to control either the voltage limit or the
current limit, or both with a 0-5 volt or 0-10 volt or 0-5,000 ohm signal. Selection of
what is controlled and how is done via the ANALOG CONTROL OPTIONS MENU
explained later in this section.
SCPI (Optional) Control is passed to the SCPI interface. For use please refer to the
SCPI Option User’s Manual.
AUTO-STEP Control is passed to the auto-step program. Instructions on how to
set up the program are in Auto-step Programming Section of this manual.
ANALOG CONTROL OPTION: When REM
ANALOG is selected as the control source, this menu
allows the user to select whether voltage is
controlled, current is controlled, or both are controlled remotely. In addition, the type of
control source may be selected. Control sources allowed are 0-5 volts, 0-10 volts, and
0-5,000 ohms.
SET POWER LIMIT The maximum output power of
the power supply can be set via this menu. To set
the Power Limit, cycle the Menu button until Set
Power Limit is displayed. Enter a limit from the keypad or the keys. Set this limit by
pressing ENTER. When the load is increased to the power level set, the Constant
Power light will illuminate and the voltage and current will be automatically adjusted to
maintain a constant power. When the power is set to less than the maximum rating of
the power supply, the alphanumeric display will always display the current output power.
AUTO-STEP PROGRAMMING This menu allows the
user to program the auto-step sequence. To enter
this program, refer to the section on auto-step
programming.
