I’m hoping someone can help me understand calibrating the NPE Runn device.
I thought the point of this device was to give an accurate speed reading, instead of relying on the speed displayed by the treadmill.
It comes factory calibrated at 5 mph, yet the calibration methods says to set the treadmill at 5 mph, so does the device then calibrate to your treadmill, so that 5mph on the treadmill display is what shows in Zwift, even though you might actually be doing a different speed?
For instance, I installed my Runn device and when I set the treadmill to 10 km/h, Zwift showed 10.3 km/h, and to get 10 km/h in Zwift I had to set the treadmill to 9.7.
So if the RUNN is properly calibrated at the factory, then I know I should set the treadmill to 9.7 km/h to be accurate.
But I see that to calibrate it, you do it with the treadmill set at 5 mp/h. Does this calibrate it to the belt movement, so that in my case, the RUNN would measure 10 km/h when the treadmill shows 10 km/h?
Surely this just makes the RUNN device inaccurate? (I’m not worried about incline)
