When you view your measurement data in tabular format, such as in View Pro or similar software, are your column headings, or field names, helpful to you? At a glance, do your field names quickly identify the data in the columns? If not, you may be relieved to know that you can change the default field names to something more recognizable.
By default, the datalogger automatically assigns a name to each field, or column, in a table. These field names are a combination of the variable name (or alias if one is defined) and a three-letter mnemonic for the processing instruction that outputs the data. For example: batt_volt_Min is likely the minimum battery voltage.
For some output instructions, the field names can be a bit more arcane, but you can easily overwrite them.
To change the default field name, use the FieldNames() instruction. The FieldNames() instruction must immediately follow the output processing instruction that has the default field name you want to overwrite.
Tip: You can see the field names that have been defined for each data table in your program. After you save your program in the CRBasic Editor, navigate to Tools | Show Tables.
I hope this information helps you identify your data for easier analysis and sharing. If you have any comments or questions, feel free to post them below.
