Using the -a flag results in an error. Everything else seem to work fine. I'm using the win32 executables.

Yes, it's a known bug, due to weirdness in the USB. I do have a fix, but the workaround is very simple, once you've run with -a, run again without -a (The calibration will be retained by the instrument).
