Copying the data of the built-in logger is done with a USB pendrive. To do this, insert a pendrive formatted in FAT32 and restart the device. Thermolog will automatically start copying data to it after detecting the pendrive. The display will show information about the progress of copying.
Once copied, the file on the flash drive will be named Termdump.BIN
To open it you need to use a dedicated PC program - Thermometer.
