When hooked up to my USB i get perfect results 90% of the time. When its only hooked up to a power source its less than 50% accurate.

Using a signal converter to try to improve accuracy but honestly it doesn't make a huge difference in accuracy. Almost seems more consistent without the signal conversion. Any help would be amazing!
