Before you send an article back to us because of a complaint or repair or fine-tuning (e.g. for calibration), it is necessary to request an RMA number. Please enclose this number with the article - without an RMA number, processing is not possible.
Here you can download the appropriate form to request the RMA number.
We are happy to provide you with our products for a non-binding test. We have a form available for this purpose, on which all the necessary data is recorded.
This form is a contract which requires a handwritten signature including company stamp to be legally binding. For this reason we ask you to let us have the completed form.
