Operation: when the monitor works normally, this light is on;2. Communication: this light is on when networking with the host;3, Over-current: when the load over-current reaches the set value, the light will be on with alarm sound;4. Over voltage: when the monitoring voltage is higher than the set value, this lamp will be on with alarm sound;5. Undervoltage: when the monitoring voltage is lower than the set value, this light will be on with alarm sound;6. Loss of power: when the monitoring voltage value is 0V, this light will be on with alarm sound;7. Standby power / leakage: when checking the voltage value of standby power supply on the machine, this light will be on. When the monitoring leakage current reaches the set value, this light will be on with an alarm sound (when two-way three-phase power supply monitors, there is no leakage monitoring function) (when one-way three-phase power supply monitors, there is no standby power to check);8. Silencing: when the silencing key is pressed for alarm, the light will be on; and the alarm sound will be eliminated;5, Key function introduction1. Setting: press this key to enter successively for parameter setting;2. "Up" and "down" keys: when viewing various parameters and setting parameters, press this key to turn pages or increase or decrease the parameter value to be adjusted;3.
