Just see and understand

From now on our tutorials will help you to understand smaller or bigger subjects about the handling of portable devices. In a first series we will show you the correct handling of the clamps and scanning heads with our MT-devices. We are working on further topics from the field of instrument transformer and stationary meter testing. We are looking forward to getting ideas, suggestions and a feedback from you. Tell us what you need to have explained.
