Safety & Warnings
The manual provides the following safety warnings and precautions:
1. Data Lines: Connections between measuring devices and external devices should use adequately shielded cables. Data lines should not exceed 3 meters in length and should not be outside buildings. Only one interface cable should be connected at a time, and double-shielded cables are recommended.
2. Signal Lines: Signal transmission lines should be as short as possible, not exceeding 1 meter in length, and should not be outside buildings. All signal lines should be shielded cables, and proper grounding must be ensured. Double-shielded coaxial cables should be used for signal generators.
3. Device Impact: Strong high-frequency electric or magnetic fields may cause unwanted signal interference, but this does not lead to device destruction or malfunction. Slight deviations in display and measurement values may occur due to external conditions.
