Question

Accepted Answer

To calibrate pressure gauges, vacuum gauges, and compound gauges, follow these steps:

Use a known reference pressure source to compare the readings of the gauges.
Adjust the gauges if there is any deviation from the reference pressure.
Repeat the process multiple times to ensure accuracy.
Document the calibration process and results for future reference.
Perform regular calibrations to maintain accuracy.
Example: For pressure gauges, connect them to a pressure calibrator and adjust the gauge reading to match the calibrator's reference pressure.
Example: For vacuum gauges, use a vacuum pump to create different vacuum levels and compare the gauge readings to the known vacuum levels.
Example: Compound gauges can be calibrated by applying both pressure and vacuum and verifying the readings at different points.
