I have a DAQ device which is reading 14 Thermocouples at 1 measurement every 4 seconds. I took around 4 hours worth of readings before stopping the experiment, the last reading was at 12:30 but I didn't stop process until 13:15. The file size is 2.5mb, any reason why it didn't continue to write data or is there a limit to how much can be written to an excel file? Any advice would be greatly appreciated.
