SBK-unexpected-data

Forewords

The SBK Datalogger generates CSV files that can be imported into spreadsheet (see this tutorial on Spreadsheet usage).

Upon condition, charting may reveal few data deviating from standard/common values.

This tutorial shows: why it happens, how to identify the data, how to fix it and what to do to avoids such situation.

The unexpected data

Drawing the data of the temperature sensor (content of the CSV) reveal an unexpected value.

By exploring the spreadsheet data, we can locate the line where appears the 180 °C value.

A close inspection reveal that "180" value is not a temperature but the next iteration number.

Conclusion:

• The iteration 153 as no value.
• The line of iteration 153 must be removed.
• Iteration 153 to 179 are missing (lot of data has not been logged).
