Ten Precautions to Note During Testing of Microcomputer Relay Protection Test Set:
1. The microcomputer relay protection test set has a built-in industrial computer and Windows operating system. Please do not turn the host power on and off too frequently.
2. The front or rear panel of the microcomputer relay protection test set is equipped with USB ports, allowing hot-plugging of USB devices (such as USB flash drives). However, please ensure that the plugging or unplugging is done after data transmission is completed.
3. To ensure the stable and reliable operation of the built-in Windows operating system, please do not arbitrarily delete or modify files on the hard drive or desktop icons. Do not arbitrarily operate, change, add, delete, or use the built-in Windows system to avoid damaging the operating system. When using a USB drive to copy data, ensure that the USB drive is clean and virus-free, and do not use the USB drive to install other software programs in this system.
4. When connecting an external keyboard or mouse, do not plug them into the wrong ports, otherwise the Windows operating system may not start properly.
5. Do not turn off the power directly while in the output state, to avoid incorrect output that may cause protection misoperation.
6. The binary inputs are compatible with both dry contacts and potential (0-250VDC). When using live contacts, the high potential (positive) side of the contact should be connected to the common terminal COM.
7. When using this instrument, do not block or seal the ventilation openings. Generally, place the instrument upright or open the support feet and place it at a slight angle.
8. It is forbidden to introduce external AC or DC power into the voltage or current output jacks of the test set. Otherwise, the test set will be damaged.
9. If the on-site interference is strong or safety requirements are high, before testing, please reliably ground the ground terminal of the power cord (3-core) or the grounding hole of the device.
10. If there are issues such as interface data errors or device connection failures during use, you can solve them by: pressing the reset button downward to reset the DSP; or exiting the running program to return to the main menu and rerun the program, then all interface data will be restored to default values.
