Hello,
I have a bike counter from the brand "perf" and I have lost my instruction manual.
I would like you to give me the calculation to determine the correct number to set so that the counter recognizes the wheel or alternatively, you could scan the manual for me.
Thank you, see you later.

Hello,
I also lost the manual, I would like to download it if possible, it would help me, thank you in advance.
For the calculation, it is done automatically after entering the outer diameter of the wheel in millimeters; either as soon as the screen lights up after inserting the battery, or you hold down the black button under the screen for more than 10 seconds at the “odo” marker.
The screen displays a 4-digit number at the bottom: the rightmost digit starts to blink and scroll from 0 to 9 until you press the black button under the screen, then the second digit from the right starts to blink and scroll from 0 to 9 until…
It goes without saying that it is necessary to know the circumference of the wheel of your bike, moped, ...
My bike has a 26-inch wheel, I am looking for the manual to get the conversion from inches to millimeters, thank you for your help.
