⚠ Special Precautions
- When using both channels simultaneously, the ground clips of both probes must be connected together. It is strictly prohibited to connect the ground clips of the two probes to different potentials, especially to different potential ends of high-power equipment or 220V/110V circuits. Doing so may damage the oscilloscope's mainboard because both channels share a common ground, and connecting them to different potentials can cause a ground loop and short-circuit the mainboard.
- The BNC input on the oscilloscope has a maximum tolerance of 400V. It is strictly forbidden to input voltages exceeding 400V when the 1X probe switch is used.
- For charging, use the dedicated charger provided. It is prohibited to use the power supply of other equipment under test or a USB connection. Doing so may cause a ground loop and short-circuit the oscilloscope's mainboard, potentially damaging it during the testing process.
- When measuring high-frequency, high-voltage signals, use a 100X probe (e.g., for ultrasonic welders, ultrasonic cleaners, etc.), or even a 1000X probe (e.g., for the high-voltage side of high-frequency transformers, induction heating coil resonators, etc.).
