Calibration

The Need

Calibration is the process of adjusting a device to ensure it produces accurate and reliable readings. Calibration is typically performed by comparing the device’s readings to a known reference and making any necessary adjustments. The calibration process typically involves making adjustments to the device, testing the readings, and documenting the results.

Calibration is important because it ensures that devices are accurately measuring the correct values. Proper calibration prevents errors in data and other readings, and can help identify any potential problems with the device or its environment. Additionally, calibration helps maintain the accuracy and reliability of the device over time, ensuring it produces consistent results.

The Process

1. Test the device to ensure it is functioning.

2. Adjust the device according to the manufacturer’s instructions for the intended deployment.

3. Set the device to the desired measurement range.

4. Record the device’s readings and compare them to a known reference or other calibrated sensor.

5. Adjust the device, if necessary, to bring the readings into the desired range.

6. Repeat steps 2 – 5 until the device is accurately calibrated.

7. Document the calibration process and results.

Third Party Notes

Calibration often needs to be specified by the buyer of hardware to a thirdparty and reports are not always given but can be asked for if required.

Calibration certificates should always be sought as a way to provide proof of the devices reliability in recording data.
