From the western part of The Netherlands. I want to calibrate my Edge 130 altimeter in my backyard which is at 1,5m below sea level. However, the input range of the manual calibration of the altimeter is only from 0 to +100m. No other options available, No Auto calibration, No option to match with the GPS height.
Running the latest firmware 3.70. Does anyone have a solution?
Of course starting at 0 instead of -1,5 is no big deal but I wonder how to calibrate on holidays in the mountains for example...
