1. The accuracy of the instrument that performs the calibration must be
greater than the accuracy of the power supply specification.
2. Set the Resolution parameter of the HP34401 to SLOW 6 digit.
3. Key in at least 5 digits for each calibration point to ensure the Power
Supply accuracy after calibration.
