Safety & Warnings
The manual includes the following safety warnings and precautions:
1. Data and Signal Cables: Connections between measuring devices and external devices should only use adequately shielded cables. Data cables should not exceed 3 meters in length and should not be located outside buildings. Only one interface cable should be connected at a time if multiple connections are possible.
2. Shielding: Double-shielded cables are recommended for data lines. For signal transmission, cables should be as short as possible and should not exceed 3 meters in length. All signal cables should be shielded, and for signal generators, double-shielded coaxial cables should be used.
3. Electromagnetic Interference: Strong high-frequency electric or magnetic fields may introduce unwanted signal components into the device through connected cables, potentially causing minor deviations in display and measurement values.
4. Temperature Protection: The device has a temperature safeguard that shuts it down if the internal temperature exceeds 75-80°C.
5. Safety Standards: The device complies with safety standards EN 61010-1, ensuring safe operation when the instructions and warnings in the manual are followed.
