1. **Multi-Waveform Generation for Diverse Testing Needs** This SKX-2000C ECG signal simulator is capable of producing multiple waveform types, including normal electrocardiogram waveforms and positive-negative triangular waveforms. It also supports flexible signal amplitude adjustment, meeting the basic testing requirements of relevant equipment and experimental scenarios. 2. **One-Click Startup with Default ECG Waveform Output** The device is pre-set to automatically generate standard normal ECG waveforms immediately after power-on, eliminating the need for complex initial configuration. This feature allows users to start related operations quickly and efficiently, saving precious setup time for daily testing work. 3. **Intelligent Power-Saving Standby Mode** Built with a user-friendly power-saving design, the simulator will trigger CPU standby mode automatically if no button operations are detected within 24 hours. It can resume full normal operation with a simple power restart, and any button press during use will reset the standby timer to prevent accidental power-saving activation. 4. **Easy-to-Operate 4-Button Control System** Equipped with four functional buttons (Select, Increase, Decrease, Confirm) plus a combination key, the device features a straightforward operation logic. The Select button switches between adjustable parameters; Increase/Decrease buttons modify values; the Confirm button validates and generates corresponding waveforms, catering to both novice and experienced users. 5. **Clear LED Indicator for Precise Parameter Selection** Four LED indicators are integrated to display different parameter codes, with the bright dot in the lower right corner of the indicator clearly marking the currently selected content. This intuitive visual prompt helps users avoid misoperation during parameter adjustment, ensuring accurate and reliable waveform output every time.
