Product testing of Electric desk leg control box
The test adopts the fully automatic test system independently developed by Jingshi, and the test tool can make a comprehensive evaluation of the power supply and control part of the control board. The test system can detect the following contents of the control board:
1. Whether each output of the power supply is normal
2. Whether there are any problems of the main power supply, with load, overload, over temperature, and short circuit
3. Whether the hardware sensors of each part of the control board are normal
4. The control board can be initialized with table legs, moving them up and down, etc.
When there is any anomaly during the automatic test, the system can promptly ring through the buzzer as quickly as possible.
