Removing references

  •    REMOVE REFERENCES...      (Active channel only) Reference readings are a common method of checking measurements against a known value.  Typically one reads sample data for a certain period, after which the instrument is switched to read some standard condition (perhaps a known temperature or gas concentration).  After the reference reading, more sample data are recorded, and the process is repeated as necessary (the LabHelper program can do this automatically, for example).  References help insure accuracy, but may be inconvenient during analyses.  This routine lets you eliminate most kinds of reference readings from a channel. 

    The Remove references window is shown above.  To use it you need to specify:

    Reference removal is performed and the new values are displayed in the plot area when you click the 'Fix references' button.  You can then undo the results, or exit the function.
