SOLUTION

• The recommended practice when measuring unknown voltage levels with a multimeter is to start with the highest range and work down.
• When measuring an unknown voltage, it’s best to start with the highest range on the multimeter.
• This prevents overloading the meter if the voltage is higher than expected.
• If the reading is low, you can then decrease the range to get a more precise measurement.
• Using a low range for a high voltage can damage the multimeter
