Samples of the trends may also be saved to a log file. Select
the time interval (from 10-1800 seconds) at which to
capture the values. Click on the “Save” button to create the
log file. The log file is saved in .csv format and may be
viewed using a spreadsheet editor such as Microsoft®
Excel. After creating the log file, the “Save” button
becomes a “Stop” button. Click on the “Stop” button
anytime to stop recording the trends to the log file. The
trending log file records the date and time when the
parameters are logged, and it records all parameters
regardless if they are selected to be plotted or not. See
