8.4 Data logging
The data logging feature permits measurement data to be written to disk
for archiving, documentation and analysis purposes. This capability can be
turned on or off by setting a check mark at the bottom of the measurement
window at the “Log data every..” position. Once enabled, measurements are
taken at the interval rate displayed in the text box at the bottom of the
measurement window. The minimum logging interval time is 5 seconds. The
maximum is 3600 seconds or one hour between recordings.
8.4.1 Selecting a data file
The data is stored in a comma separated value ASCII text file using the
path and filename shown at the bottom of the Measurement window. There
may not be enough room to display the entire path as indicated by leading
dots. Data logging filenames can be set using the Measurements - Data File
sub-menu. Selecting this menu displays a dialog box that allows the file
name and file options to be selected. The file name can be entered directly
or selected using the
button. If an existing data file is selected,
data will be appended to it if the Append mode is selected. If the Overwrite
mode is selected, the existing data file will be overwritten with new data.
