Page 6: Introduction
2. Introduction The DEFECTOMETER M 1.837 is designed for crack testing. It is characterised by a very high sensitivity to surface defects and by simple, intuitive operation. Compared to the predecessor model, the DEFECTOMETER 2.837, it has numerous new features. -

- and therefore the sensitivity - of the device. A gain of 6 dB corresponds to doubling the signal amplitude. Setting the defect threshold with the Discriminator button The DEFECTOMETER M 1.837 allows the user to set a maximum permitted defect level (threshold). A signal above this preset threshold value is visually indicated by a red LED. -

Need help?
Do you have a question about the DEFECTOMETER M 1.837 and is the answer not in the manual?
Questions and answers
I will use a Defectometer M 1.837 as an instrument for my thesis work. I need to connect this device to my PC, but i **** not able to collect the information because the CD was lost and i cannot download the application anymore. Is it possible to download the application without the CD?
