biascontrol

Select which power supply to control, using the menu.

For expert use, set the desired voltage. Otherwise, check the "Use Default Settings for Voltage" box, and the appropriate value for each power supply will be automatically used.

Press the green Ramp Up button. There is a confirmation window that allows the ramping up to be cancelled if there is a mistake in the selection of voltage or power supply. Also, if the FEC voltages are off or out of range, Ramp Up will automatically be cancelled.

rampconf

After pressing OK on the confirmation window, you should see a small window that displays the voltage and current during the ramp up steps.

The Ramp Up procedure works only if the power supply is OFF or at 0 volts. To change the voltage, Ramp Down first, and then Ramp Up to new voltage.
