Should you rely on normalized VALUE alone?

• A. Yes — VALUE is enough.
• B. RAW_VALUE is not useful.
• C. RAW_VALUE is irrelevant.
• D. No — always check RAW_VALUE for real evidence.

Answer: (D)

Normalized readings are helpful for quick interpretation, but they can mask the true state because they apply calibration and scaling that may hide anomalies or drift. The raw measurement provides the actual evidence of what the sensor is reporting, without those transformations. By checking the RAW_VALUE, you see the exact data the system received, which helps you detect out-of-range values, saturation, noise, or sensor drift that a normalized VALUE might obscure. So, for reliable verification and troubleshooting, you should use RAW_VALUE as your primary evidence and not rely on normalization alone.
