ESD test for electrostatic discharge
Test ambient temperature: 25℃
Test ambient humidity: 50%
Test process: Carry out contact and air discharge on the periphery of the iron frame and the display area of the serial port screen in turn, and observe whether the screen has abnormal working phenomena such as reset restart, black screen, white screen, communication interruption, and other abnormalities.
Discharge type | Discharge value | Result |
Contact discharge | ±6KV | Working properly. |
Air discharge | ±15KV | Working properly. |
Note: All tests are conducted when the products are exposed. In the actual use process, when the serial port screen is assembled on the user equipment, the screen and the equipment are kept well-grounded, the ESD performance of the whole machine will be better. | ||
EFT Test
Test ambient temperature: 25℃
Test ambient humidity: 50%
Test process: The power supply line supplies power to the screen through the power supply after the pulse Group generator is coupled with the pulse Group; the serial port signal line carries out serial port communication with the screen through the signal after the pulse Group generator is coupled with the pulse Group; and the screen is observed whether abnormal working phenomena such as reset restart, black screen, white screen, abnormal communication, and communication interruption.
