In Vernier Video Analysis, velocity is calculated using a numerical derivative. The default calculation uses seven points, three on either side of the position point of interest, to calculate the object's velocity at the point of interest (for addit...
Some Vernier devices that connect by USB may show connection failures in macOS 11 and 12 (and newer). This rare connection issue is seen on both Intel and Apple Silicon computers.
We have seen the USB connection drop momentarily, so that the dev...
When collecting full spectrum data from any of Vernier's Go Direct spectrophotometers listed below, the software will report more values when connected by USB than when connected by Bluetooth. This is done intentionally to optimize Bluetooth perform...
