What condition is indicated by the simultaneous flashing of display readouts on an electronic digital multimeter?

The simultaneous flashing of display readouts on an electronic digital multimeter typically indicates an overload condition. This happens when the input signal or voltage exceeds the range that the multimeter is capable of measuring. When the device encounters this situation, it alerts the user through flashing indicators, suggesting that the measurement cannot be accurately displayed and that the device is receiving a voltage or current that is beyond its specified limits. It is essential for the user to recognize this signal to prevent further damage to the multimeter and to ensure proper operation in future tasks.

In contrast, a low battery condition would often lead to irregular readings or dim display rather than simultaneous flashing. Calibration needed warnings would usually not cause a display malfunction but instead show inconsistent readings. Connection failure may manifest as a lack of display or erroneous readings rather than the simultaneous flashing of readouts. Therefore, understanding this indicator helps users quickly assess and react to measurement issues efficiently.
