However these reference points may change subsequent to calibration.

Please follow the steps to cali. Unless the sample is expected to be above pH 7 basic buffers should not be used as their pH value quickly changes by absorbing CO 2. In a sense it level-sets the meter at the correct level much like a scale needs to be placed at exactly zero to produce an accurate weight. After 1st point calibration you turned the meter off and turn it back on for the 2nd point calibration. In your case it sounds like a pH 200 and a pH 400 will work well for most of your work. Temperature-related issues When reading a sample make sure that calibration and sample readings are done at the same temperature.
