2. Informació de seguretat

To ensure safe operation and prevent damage to the device, please read and adhere to the following safety precautions:

• Seguretat general: Always operate the device within its specified voltage, current, and frequency limits. Do not use the device if it appears damaged or is not operating correctly.
• Perill de descàrrega elèctrica: Avoid contact with live circuits. Use caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC, as these pose a shock hazard. Ensure probes are properly insulated.
• Probe Connections: Connect the ground lead of the oscilloscope probe to earth ground before connecting the probe tip to the circuit under test. Disconnect the probe tip first when finished.
• Seguretat de la bateria: Use only the specified charging adapter. Do not expose the battery to extreme temperatures or disassemble it. Dispose of batteries according to local regulations.
• Medi ambient: Operate the device in a dry environment, away from moisture, dust, and direct sunlight.
