Answers 1 & 2 are Almost correct. But the Statement "Comparators are not used for calibrating the gauge" is not corect. If the standard test gauge used for comparing is a master test gague or having the traceiablility...Pr. Comparators are also can be used for the Calibration. In fact any home made pressure generating source also can be used for the calibration if we use the Master Test Gauge (certified) as reference.
For you information Pressure generating sources dont need any certifications or Traceiabilty.
