1. The microcomputer relay protection tester and Windows operating system are built in. Please do not switch the power supply of the host too frequently.

2. USB port is installed on the panel or back of the microcomputer relay protection tester, which allows hot dialing of USB port devices (such as U disk, etc.), but it must be done after data transmission.

3. In order to ensure the stable and reliable operation of the built-in Windows operating system of ipC, please do not delete or modify the files on the hard disk and the ICONS on the desktop. Please do not operate, change, add, delete or use the built-in Windows system at will, so as not to damage the operating system. When using USB disk to copy data, please make sure the USB disk is clean and virus-free, and do not use USB disk to install other software programs in this system.

4. When attaching the keyboard or mouse, do not plug in the wrong port, otherwise the Windows operating system cannot start normally.

5. Do not turn off the power directly in the output state, so as to avoid the protection misoperation due to the output error during the shutdown.

6. Open input is compatible with empty contact and potential (0-250VDC). When using live contact, the high end of contact potential (positive pole) should be connected to the common terminal COM terminal.

7. When using the instrument, do not block or close the air vents of the fuselage. Generally, the instrument should be placed standing or open the supporting feet and placed slightly at an incline.

8. Do not introduce external AC/DC power into the voltage and current output jack of the tester. Otherwise, the tester will be damaged.

9. In case of strong field interference or high safety requirements, the grounding end of the power line (3 cores) should be reliably grounded or the grounding hole of the device before the test.

10. If interface data is wrong or the device cannot be connected during use, it can be solved as follows: press the reset button down to reset the DSP; Or exit the running program and return to the main menu, and then rerun the program, all the data in the interface will be restored to the default value.
