Spirit System

Could you please do this:
Set General/Position to Horizontal (0°)

Then perform calibration with CTRL+ALT+U again.

Set General/Position back to your original position.

Then check if the problem is solved (possibly after restart). If no, I will send you PM with other solution.

Sorry can’t send 4ds file as the computer I use for spirit setups is not online

Bear with me I’m trying to find a way to get the file to you

Re calibration at horizontal (0Deg) made no difference,

I am using an iPad Online just now , I assume there is no software got iPad ?

Ah, please check your PM.

App for iPad is integrated in the Wifi-Link.

Thanks to ZeXx86 All sorted , again thanks to everyone who contributed

Kind regards Kenny d

You are welcome!
The issue was resolved by resetting calibration data to factory defaults.

and how is this done ?

With key shortcut, but it is not public, because people would try it without real need to do this.

true

If updating from 2.x to 3.x, is the -U calibration required?
