The microcomputer relay protection tester is also called the microcomputer relay protection tester, the microcomputer relay protection tester, the relay protection tester, etc. It summarizes the advantages and disadvantages of the current domestic similar products, and makes full use of the modern advanced micromotor technology and the realization of the device. A new type of miniaturized microcomputer relay protection tester, which has the advantages of simple operation, high reliability, and high performance-price ratio.

 

       When doing the test, you must pay attention to the following matters when operating the microcomputer relay protection tester:

 

       1. Pay attention to the safety of operation, prevent electric shock accidents, and try to be a guide by the long-term electrician workers when operating;

 

       2. The ground terminal of the host is reliably grounded to avoid induction of static electricity and reduce electromagnetic interference;

 

       3. External current is forbidden, and the voltage is connected to the current and voltage ports of the tester, otherwise the tester will be damaged;

 

       4. When starting the tester, it is recommended to warm up for 2 minutes, wait at least 1 minute after shutting down and then turn it on again, otherwise it will damage the tester or cause the instrument to work abnormally;

 

       5. The normal ventilation of the tester should be ensured. Do not block the vents and fans at the bottom and tail of the instrument to avoid overheating.
