If the measured voltage range is unknown, set the range switch to the highest position first, then adjust to the appropriate range based on the displayed value 2. If "1" appears on the display, the range has been exceeded; switch to a higher range setting 3. Input voltage must not exceed 50V; exceeding this may damage the meter circuit 4. When measuring high-voltage circuits, avoid contact with live circuits to ensure personal safety
