1. Safety Information (Before using this product, please read the safety information in advance) Safety Terms Terms in this manual (The following terms may appear in this manual): Warning: Warning indicates conditions or practices that could result in injury or loss of life. Caution: Caution indicates the conditions or practices that could result in damage to this product or other property. - Page 4 Warning: To prevent electric shock or fire, use a suitable power adapter. Refer to section "General Technical Specifications" for further information relating to the power supply. Warning: The two channels of the oscilloscope are non-isolated channels. Note that the channel should use a common reference when measuring, and the ground wires of the two probes cannot be connected to two non-isolated places with different DC electrical levels, otherwise it may cause a short circuit due to the ground wire connection of the oscilloscope probe.
