🔧 CALIBRATION vs VERIFICATION vs VALIDATION – Know the Difference! 🛠️ Ever wondered what the real difference is between Calibration, Verification, and Validation when it comes to instruments and systems? Let’s break it down 👇 📏 Calibration It's all about accuracy! A Pressure Gauge (UUT) is compared to a reference standard (like Fluke 754) to determine if it’s reading correctly. ✅ Verification Here, we check if the calibrated instrument meets specs. For example, an error of -19 mmWC at 1500 i
