START

1. The method of use is very simple and easy.
2. Press the "Start Inspection" button and check the checklist you see.
3. For accurate measurement, measure 1M PC and 20cm away from the screen.
4. It is best if you do it in a dark room or semi-dark room for optimal examination.
5. Cover one eye when measuring and measure the other eye the same.
6. When you close your eyes for 3 seconds and open them, judge the darkness that appears momentarily.
7. When the measurement is finished, press "ESC" for the PC and "Back" for the mobile.
