I calibrated the quad to 2.0 when input was 2.6, I’ve saved the calibration and settings and restarted the quad. My Input is still at 2.6V and the Quad displays Vpp: +1.30V, Vdc: +1.32V now in the DC0.5V range.
After entering the calibration again, before I change anything the Voltage is displayed as 2.50V in the 0.5V Raw (Input still 2.60V). I leave it as it is. Save the calibration and Settings again. Restart the Quad: Vpp: +2.10V, Vdc: +2,14V (Input 2.60V).
And again. I enter calibration mode, choose the 0.5V range, calibrate the input 2.60V to 2.60V. Save the calibration and settings. Restart the Quad, get Vpp: +2.30V, Vdc: 2.34V.
When entering the calibration mode the quad seems to reset all settings, - is this correct? I again enter the calibration mode, get 2.48V displayed, I change it to 2.90V. Save and restart. Now I get Vpp: 2.84V, Vdc: 2.88V.
I calibrated to 2.70V, saved and got: 2.42V instead of the 2.6V.
I calibrated to 2.80V, saved and got: 2.66V.
calibrated to 2.74V, saved and got: Vpp: +2.54V, Vdc +2.58V
calibrated to 2.76V, saved and got: Vpp: +2.58V, Vdc +2.62V
calibrated to 2.78V, saved and got: Vpp: +2.62V, Vdc + 2.64V
Changing Input to 5.0V, get Vpp +5.30V, Vdc +5.32V
It’s completly impossible for me to get reliable readings…
The parameters are stored, there must be any other bug in the calibration?
