NOTE: The date and time is recorded for every data sample. Up to 32 signals can be selected

per log file.

The text (rows and columns) can be copied and pasted into a spreadsheet program for analysis;

e.g., graphing.

Recommended size is up to seven signals and a maximum one thousand entries, as very large

log files may not be viewable. If the datalog screen comes up blank, the log is too large to be

displayed.
