Did that too. Waited far more than 10 secs. Same results.

Doesn't appear to have erratic figures, did that too. Even did the adjust throttle procedure of the 690, power on, rotate gently till full, then back, switch off, always looking at the voltage value and % pointer in tuneecu... One interesting detail is that at full throttle the voltage is 4,07volts instead o 3,91v or so... been told to ignore this, but it seems rather unusual.
