BioWelder TC records operations for its on-going operation and saves them .
A circular buffer is provided for this purpose . If the memory is full and a new log
appears, the oldest log is deleted permanently and the new log is saved . Depending on
setting and operating mode, it is possible that recordings are never overwritten even
if the device has executed thousands of welds .
These recordings can be copied to a storage medium through the Web browser
or through the touch screen . See Chapter 6 .2 .10 Log for touch screen or Chapter 6 .3 .9
Log for the Web browser .
The output format of the weld log is CSV or html . To read a csv file, various tabular
calculation programs such as Microsoft Excel or OpenOffice Calc can open these files
without problem or import functions for databases can be written . To open a html
file, use a web browser such as Firefox, Chrome or Internet Explorer .
The html file has a self-validation function built in . This function prevents acciden-
tally altering of the data stored inside the html log file . At the end of the file it shows
either "Valid" in green or "not Valid" in red .
A criminal action cannot be prevented with this self-validation function!
®
The internal memory of the BioWelder TC has a capacity of around 50'000 Weld Logs .
If the memory is full, the oldest entries will be overwritten without warning .
The customer is responsible to archive the downloaded weld logs .
