Power outage; it is necessary to check the reason for the power failure in the relevant equipment
This situation could be due to the ammeter being damaged, or it might be that an extremely high resistance has been suddenly connected to the circuit – for example, a voltmeter – resulting in very weak current flow in the circuit. It’s also possible that the ammeter is short-circuited; even though its internal resistance is very low, it can still get short-circuited.
There are many reasons why an ammeter suddenly returns to zero. First: the phase wire has come loose; second: the current circuit is damaged; third: there is a missing phase. Each cause requires a different approach

If the ammeter suddenly returns to zero, it could be due to a malfunction in the ammeter or a power outage. When dealing with this situation, do not rush to press the stop button; first check whether the main unit has stopped operating. If it has stopped, then it’s likely due to a power outage or a circuit breaker trip. If the unit is still running and all components are functioning normally, then it’s the ammeter that is malfunctioning, and an electrician should be called to handle the issue.

The ammeter may be damaged; cut off the power immediately and call an electrician and a technician
Jump out of the car. Perform an emergency stop.
