Implementation Tips for Napco XRF Analyzers
Quick-Start Best Practices
- Place the analyzer on a stable, vibration-free surface (avoid counters near stamping machines or heavy foot traffic).
- Use the provided sample cups and protective films for loose scrap or irregular pieces to prevent contamination and ensure repeatable results.
- Perform daily energy calibration (takes <60 seconds) using the included standard reference block – this guarantees long-term 99.99% accuracy.
- Train all staff in under 2 hours: the touchscreen interface is designed for non-technical users (jewellers, cashiers, security officers).
- Connect to your network or Wi-Fi for automatic software updates and cloud backup of test reports.
