Hi!
Unfortunately I have two problems:
1. The accuracy of the distance measurement is about 3...8mm. The measured distance is greater than the real one up to 8mm. The described accuracy is about 2mm. There is great mismatch between the described accuracy and the real one.
2. The tilt sensor shows 7degrees on the horizontal surface and I cannot calibrate it. Actually there are two places were I can see tilt angle. On of them is on the left of the display and the second one appears when I activate indirect measurement mode. It is strange but the second one is affected by calibration algorithm, but the first one not. How can I calibrate both of the values?
And there is strange description of the calibration algorithm. It is not clarified in which surface (horizontal, vertical) I shall do this calibration. And it is described that I shall rotate the device for 180 degrees. But it is not clarified over which axis I shall do this.
So I will be glad to see answers in order to make functionality of my device correct.
Thank you with advance,
Best regards,
Alex

Thanks very much for your below information.
As our usual experience, if the package is with problem, we need the returned package for resend /refund, also for all the products before shipment, we have QC but it may be damaged in the long shipping way.
Due to considering that if sending back, it will take a long time, so we suggest if the item can be repaired at your side, then we offer discount.
Or what is your opinion ?
Вот теперь думаю что он имел в виду под словом дисконт и, если таки отправить - будет ли следующая лучше )
