Note the tabular format of the data as well as the column headings and the time stamps (the
third column in Notepad and WordPad, and Column C in Excel).
Like Record data, Data Logs
comprise three sets of readings (IR Temperature, Air Velocity and Air Temperature) that are
expressed in default units and displayed in chronological order.
Unlike Record data, the
time stamps of Data Logs begin when you started data logging and stop when you stopped
logging. Also, unlike Record data, Data Log data points are captured at the sampling rate you
selected (or the previous default sampling rate, if you chose not to select a new rate) before
beginning a data logging session.
Finally, note that when you upload data logs, all logs in the instrument’s memory are
uploaded, not just the logs of your most recent session.
To clear the data logging memory
in the CIH20DL, follow the instruments for the “Clear Data Logging Memory” box of the
flowchart (Fig. 8) on p. 13.
Instructions for optimizing the graphical presentation of data logs are beyond the scope of
this manual. Using Excel, rather than Notepad or WordPad, to open data log files offers the
most options for viewing flexibility.
