More Details

LCD/LED Screens
Results will vary between the three reference marks on an LCD/LED screen. This is due to the way the screen is updated, generally starting from the top and ending at the bottom. The minimum result possible at the bottom of the screen should be 16ms (t = 1 / f = 1 / (60 Hz) = 16.67 ms). We recommend using the middle reference mark for recording results.



Projectors
When using a projector simply turn the device around so that the photo sensor on the back of the device is positioned inside one of the displayed reference marks. We recommend using the middle reference mark for recording results.


Fluctuating Results
This can be caused by a timing difference in the back light and screen refresh rate. In this instance we recommend using the lowest value. For best results we also recommend setting the screen to the highest brightness and reduce ambient lighting where possible to ensure the most accurate readings.


Proudly designed and made in the UK.
