Problem:Calibrating digital and analog pressure gauges requires different approaches. Digital pressure gauges often have built-in microprocessors, which can introduce errors or require special procedures, while analog gauges require more manual adjustments.
Solution:
Calibrate Digital Pressure Gauges Using a Traceable Standard: When calibrating digital pressure gauges, always use a calibrated pressure standard that is traceable to national or international standards. Follow the manufacturer’s instructions for adjusting or calibrating the digital display.
For Analog Gauges, Perform a Visual Calibration: For analog gauges, compare the readings with a known reference pressure source. Ensure that any mechanical parts of the gauge (such as springs) are not worn, as this can affect readings.
Cross-Check Calibration Results: If possible, calibrate both digital and analog gauges using the same pressure source to compare results and ensure accuracy.
