When setting the range on a DMM for voltage measurement, you should set the voltage range ___ the expected voltage.

When setting the range on a Digital Multimeter (DMM) for voltage measurement, it's essential to select a voltage range that is slightly higher than the expected voltage. This approach ensures that the multimeter can accurately read the voltage without risk of overloading or damaging the device.

Choosing a slightly higher range allows the meter to function within its optimal operating parameters, ensuring both accuracy and safety. For instance, if you expect a voltage measurement of around 12 volts, setting the DMM to the next available range, such as 20 volts, allows for an accurate reading while accommodating any slight fluctuations. This practice also helps prevent potential errors that can occur if the measured voltage exceeds the selected range, which could lead to inaccurate readings or even harm the meter.

By using a range just above the expected voltage, you are not only ensuring a safer operation but also maximizing the precision of your measurements.
