Dear, mechanical timers may have an error of 1-3 minutes, so if you need precise timing, we suggest you buy electronic timers.

Attention: Rotate the timer clockwise to the zero mark, then counterclockwise to the desired time. The timer will emit a clear ring when the time is up. That is, you need to rotate to the bottom, then turn back. If the ringing is not at 0 but at about 1 minutes, this is normal because it is mechanical. Within 3 minutes is normal. If you need very precise time, only electronic timers can be precise to the second. This product will ring within the first 3 minutes after you receive it.In the future, when using it, please remember not to turn it the wrong way, as it is wound! Please pay attention!!!
