Although the control box can often be operated manually, in order to save time, we can also use instruments to operate the control box. The following small series will give you an analysis of the key points to keep in mind when using instruments to operate the control box.

1. For the safety of operators and instruments, ensure that the instruments are well grounded before they can be used.

2. When preparing for the test, the ground wire shall be connected first, and then the ground wire shall be removed after the work is completed.

3. Instruments that can operate the control box generally have to withstand the current impact with the power supply of 50A.

4. Do not plug or unplug any wiring when powered on.

5. When outdoors, the instrument must not be exposed to the sun for a long time.
