The current can be accurately determined using a digital ammeter by first selecting the appropriate measuring range on the ammeter that is higher than the expected current. The display on the ammeter will then show the current reading. If the current is higher than the selected range, the display will show an overload indication. In this case, the measuring range can be adjusted to a higher range to accurately measure the current. If the current is lower than the selected range, the display will show a lower reading, and the measuring range can be adjusted to a lower range for a more accurate measurement. **
