Instruction Manual
Examples
The sample shown below depicts data logging occurring every five seconds with the data written to
a data log file called DataLog1.txt. When this file is 2 Kb in size, a new file will be started. Because
the data log files are written to the RAM0 area, these files are not saved when power cycles to the
device.
The current file name is displayed on the top section of the screen, along with the current file size
and the free space in the RAM0 area.
The
File List
page lists the log files created and stored in RAM. The file names begin with the
file name entered in the
Log Files
page. The second part of the file name, shown below as
...20070815... is a date stamp indicating the date the file was first created. The last three digits,
shown in the sample below as 2F9, are a hexidecimal representation of the minutes past midnight.
Converted to decimal, 2F9 is 761, indicating this file was created 761 minutes past midnight on 15
Aug 2007, or at 12:41 pm.
Because the last three digits of the file
name represent the time in minutes, set the
maximum file size and log rate so that two
files are not created within the same minute,
causing an error -70 (Duplicate Directory
Entry Error).
In the sample shown, 16 register entries
logged every second to a maximum file size
of 1 Kb fills up the file in less than a minute.
