voltage set points and current set points are set by the front panel potentiometers and over
voltage trip and over current trip are set with the keypad.  With keypad control, all four inputs
are set with the keypad.  By selecting external program, all reference inputs are set with the
analog inputs at terminals 3, 22, 4, and 23 of connector JS1.  See Section 3.4, for connecting
external reference inputs.  By selecting remote, all reference inputs are set over the RS232
network.
  

3.1.1.4 Calibration Commands

Figure 3.15 describes the calibration commands.  Calibration commands allow calibration of five
digital potentiometers, display of the firmware and hardware revisions, and reset the digital
potentiometers to the factory calibration settings.  All of these commands can be made when the
power supply is in either the standby or power mode state.  Front panel calibration commands
are available for both the master and slave modules. 

To enter the calibration commands, press menu and then press item 6 times.  Cal (calibration)
will flash in the voltage display.  Press 1, 2, 3, and 4 on the keypad and then press enter or press
clear to exit the calibration command menu.  Upon entering the calibration commands, the
output voltage will be displayed in the voltage display, the potentiometer setting, P0 to P255,
will be displayed in the current display, and the digital potentiometer, 1, will be displayed in the
memory display.  Potentiometer 1 adjusts the gain of the voltage feedback amplifier,
potentiometer 2 adjusts the input offset voltage of the voltage feedback amplifier, potentiometer
3 adjusts the gain of the current feedback amplifier, potentiometer 4 adjusts the input offset
voltage of the current feedback amplifier, and potentiometer 5 adjusts the gain of the reference
which is used for the digital to analog and analog to digital converters.

Pressing the item key advances control to potentiometer 2.  The output voltage will be displayed
in the voltage display, the potentiometer setting, P0 to P255, will be displayed in the current
display, and the memory display will show 2 .

Pressing the item key again will advance the control to potentiometer 3.  Now the output current
will be displayed in the current display, the potentiometer setting, P0 to P255, will be displayed
in the voltage display, and the memory display will show 3. 

Again pressing item will advance to control potentiometer 4.  The output current will be
displayed in the current display, the potentiometer setting, P0 to P255, will be displayed the
voltage display, and the memory display will show 4 .

To advance adjustment to potentiometer 5, press the item key again.  The output voltage will be
displayed in the voltage display, the potentiometer setting, P0 to P255, will be displayed in the
current display, and the memory display will show 5.
