Efento sensor calibration

Description

Calibration Objective

The primary goal of calibration is to ensure the accuracy and precision of measurements and results generated by the [Device Name/Model] within its specified operating range (e.g., $0-100\text{ units}$ or 10∘C−50∘C).

Calibration aims to achieve:

1. Verification of the device’s parameters against factory standards or ISO/ASTM norms.

2. Correction of detected deviations through hardware or software adjustment.

3. Minimization of systematic error to maintain the reliability of the measurement data.

Methodology (Calibration Procedure)

The calibration process is performed according to the standard procedure [Procedure Number or Industry Standard, e.g., ISO/IEC 17025], utilizing calibration standards (etalons) with documented measurement traceability.

1. Preparation: The device is powered on and thermally/operationally stabilized for [Specified time, e.g., 30 minutes].

2. Zero Point (Offset): Measurement and adjustment of the reference point (zero).

3. Linearity Test: Measurement at [Number] points distributed across the operating range (e.g., $25\%$, $50\%$, $75\%$, $100\%$ of the range) using certified standards.

4. Error Calculation: The measurement error is calculated based on the results:

   E=Vindicated​−Vstandard​

5. Adjustment: If the error exceeds the acceptable tolerance limit ([Tolerance Value]), corrections are applied.

6. Final Verification: After adjustment, a new series of measurements is performed to confirm compliance.

Calibration Result and Documentation

Upon successful completion of the calibration, the device status is updated to Calibrated.

• Calibration Certificate: A document is generated confirming the procedure, including:

  • Date and technician name.

  • Environmental conditions (temperature, humidity).

  • List of standards used.

  • “Before” and “After” results of the adjustment and the calculated Measurement Uncertainty ($\pm U$).

• Device Status: The device is labeled with a sticker indicating the calibration date and the next calibration due date ([Date/Frequency, e.g., 12 months]).

Next Steps (Schedule)

The next calibration is scheduled for [Date of Next Calibration]. The user is obliged to:

• Follow the operating instructions to preserve the validity of the calibration.

• Notify service personnel immediately in case of suspected damage or incorrect readings before the due date.
