All the examples I've read are 3-4 digits, and no negative values. I understand the concept to incrementally change the settings, but no matter how I plug it into my computer and/or turn it on, it never shows up as a device on my Explorer options to I can't get to the file to modify it. Please let me know how to get into the settings to update the calibration numbers.
