Why is it important to use the correct range on a measurement device?

Using the correct range on a measurement device is crucial for preventing damage to the tool and ensuring accurate readings. When a measurement is taken within the appropriate range, the device operates within its designed specifications, allowing it to provide precise and reliable data. If a device is set to a range that is too low for the measurement being made, it can lead to display overload, potential physical damage to the device, or inaccurate results due to saturation. Conversely, setting the range too high can result in a loss of resolution, making it difficult to see small fluctuations in the measurement.

Moreover, utilizing the correct range helps maintain the longevity of the measurement equipment. Tools like multimeters and oscilloscopes have internal components that can be adversely affected if subjected to electrical inputs outside their designed operational range. Hence, using the correct measurement range is essential for both the accuracy of readings and the durability of the instrument.
