Operate on the Measurement Interface: _x000D_ (1) Long press the "Set/Switch" key for 5S._x000D_ (2) Short Press the "Set/Switch" Key: You can view the current voltage(2), current, leakage current ; if 10S no operation, automatically return; Back to the voltage display interface._x000D_ (3) Short Press the "clear/query" Button: You can view the total faults number of times in turn (at this time, overvoltage/undervoltage/overcurrent/leakage indicators are at the same time_x000D_ on, overvoltage, undervoltage, overcurrent, leakage; Failure Times: If 10s without operation, it will automatically return to the voltage display interface._x000D_ (4) Long Press the "clear/query" Key for 5S: Clear all faults times._x000D_ (5) Short Press the "/Mute" Key: Can mute the buzzer sound._x000D_ (6) Short Press the "test" Button: Perform leakage function test._x000D_ 2. Operate in the Setting Interface: _x000D_ (1) Short Press the "Set/Switch" Key: Switch and set the overvoltage setting value, undervoltage setting value, overcurrent setting value, and leakage setting value in turn._x000D_ (2) Short Press the "/silence" Key: You can adjust the currently set value increase._x000D_ (3) Short Press "": You can decrease the currently set value._x000D_ (4) Long Press the "Set/Switch" Key: Exit the parameter setting. ; When the automatic reclosing power supply protector wiring is installed correctly, please connect the power supply. Turn on the "master control switch", and the automatic reclosing power protector will immediately turn on the circuit. Press the "Test" button, the auto-reclosing power protector will cut off the circuit, and the leakage indicator will be on, and the power will be restored automatically after 30 seconds. This means that the auto-reclosing power protector is working properly. At this point, you have correctly installed the Auto "Reclosing power supply protector", you can rest assured to enjoy the safety and convenience brought by automatic reclosing leakage protection.
