The yellow light on the instrument indicates tripping.

The trip indicator of smart meters is yellow, which usually lights up only when the load switch is turned off, but usually goes out. It is suggested to check whether the remaining power of the smart meter is zero or reaches the set lower limit. If the remaining power of the smart meter is zero or has reached the set lower limit, the user's power supply may be cut off and the trip indicator light will always be on.

It is normal that the electric meter will make a slight sound when it is running. If the instrument is loud, it may be caused by the aging of the internal accessories of the instrument or the drying of the rotating gear. In this case, it should be sent to the electric power department for inspection or replacement of new accessories.
