Calibration Mistakes
Calibration is often used as a reaction, not as a verification tool. This leads to unstable analyzers and false confidence.
Truth:
Calibration cannot fix sampling, moisture,
or process instability.
Common Mistakes
- Calibrating unstable analyzers
- Using poor-quality span gas
- Ignoring trends before calibration
- Over-calibrating to chase readings
- No verification after calibration
Correct Calibration Mindset
1) Stabilize process and sampling
2) Observe trends over time
3) Apply calibration gently
4) Verify with independent checks
Audit & Compliance Risk
Excessive calibration hides real problems and increases audit failure risk. Regulators expect stability, not constant adjustment.
