Hi, Does anyone know if the TOL-15571 supports any kind of data reading, or is the recorded data only available on the screen? I have tried to see, if the device is recognized as a serial device by Matlab, but no luck.

Here it says "In addition to the main numeric measurement interface, you can also toggle to voltage and current bar graph interfaces (because who doesn’t like a good graph?), quick charge identification mode, wire group impedance measurement, and a simple settings screen. And with the recording option, you can easily record your data. " ---

Share a method if you figure one out; I can’t get anything useful to happen
