Please go to a quiet room, bring microphone to your keyboard (notebook microphone is usually ok) and press any key loud (making meter go red) 10-20 times not faster than once per second in a white textarea.
Please choose delay that is not less than recommended: 30, 50, 70, 100, 130, 160, 200. Please make sure that you type text in a quiet room and there is low background noise detected by the meter. Also, make sure that microphone is close to your keyboard (usually it is ok to use notebook microphone) and that loud kepresses make the meter red. Warning. Calibration will work only on HTTPS version of this site. Replace HTTP with HTTPS in the URL. |
