Sunshine DT-17N constantly turns on and off with a beping, help
Hey I have been measuring batteries normally, and everything was working perfectly before. Today, when I turned it on in any mode, the screen flickers and makes a constant beeping sound. All the icons on the screen light up when it flickers.
What can i do? The batery is not the problem (I think)

Hi @joanesau,
Have you checked if the battery is OK and is securely inserted and the battery terminals aren't corroded?
