Why is my vacuubrand DVR 5 Measuring Instruments display alternating on and off?

The display might be alternating on and off because the internal overload protection is activated due to thermal overload. Ensure adequate ventilation to lower the ambient temperature. If the issue persists, the device may be defective and require factory repair.
