This page can be used to calculate the gain and offset for a Vesta sensor to ensure that data from the sensor is accurate. The instructions are written for a temperature sensor, but the worksheet can provide this information for any sensor if the input is formatted correctly.
How to Use the Worksheet
Please adhere to the following rules about entering data into the worksheet. Failure to do so can lead to inaccurate or false results.
When entering data into the worksheet, please ensure that the values you enter are:
- Numeric. The worksheet cannot process text information, so ensure that all input is purely numeric.
- In the same units. If you enter the data into one cell in degrees Celsius, you must enter the data into all cells in degrees Celsius. If you enter data in different units, your results will be incorrect.
How to Use Gain and Offset
Gain and offset are factors for correcting raw input to account for inaccuracies and faults in the sensor. Once you have found the correct gain and offset, you can accurately calculate correct data values from a sensor.
Gain is multiplied by the sensor's raw data value to achieve a more accurate result. Offset is added to the product of gain and raw input to further correct inaccuracies.
You can enter the gain and offset for a calibrated sensor into the Configure I/O tab of your Vesta user interface. This will make your data and calculations more accurate.
