Problem:Applying calibration procedures incorrectly is a common issue in pressure calibration. This can occur if incorrect calibration standards are used, improper connections are made, or wrong calibration methods are applied.

Solution:

• Follow Manufacturer Guidelines: Always adhere to the manufacturer’s calibration instructions and standards. Use the correct reference equipment for calibration and follow the recommended procedures.

• Train Calibration Technicians: Ensure that personnel performing the calibration have the necessary training and experience. Calibration technicians should be familiar with the instrument being calibrated and understand the calibration methods in detail.

• Cross-Verify with Multiple Methods: If possible, verify pressure readings using multiple methods, such as comparing results from a deadweight tester and a digital pressure calibrator. Cross-checking ensures that the calibration procedure is correctly applied.
