Method for monitoring sliding contacts

A measuring system for measuring a sample in an automated analysis machine, the measuring system comprising a measuring device for recording measurement values of a measured variable and a first controller and a second controller for processing the measurement values, wherein the measuring device and the first controller are movable relative to the second controller, and the measurement values are transferable from the measuring device to the first controller, wherein:

• the measuring system comprises a sliding contact system having sliding contacts,
• the measurement values are transferable from the first controller to the second controller via the sliding contacts, and
• the measuring system comprises an error counter for capturing errors occurring during a transfer of measurement values from the first controller to the second controller via the sliding contacts.
