The term that refers to the precision of measurement controlled by moving the decimal point on a digital multimeter (DMM) is resolution. Resolution indicates the smallest change in a measurement that can be detected by the DMM. When the range is set appropriately, the resolution of the DMM allows it to display measurements with a specified number of significant digits, affecting the clarity and precision of the readings you obtain.

For example, if a multimeter is set to measure a lower range, it can show more decimal places, providing a more detailed measurement. Conversely, if it's set to a higher range, the measurement might appear with fewer decimal places, potentially sacrificing some precision. Thus, understanding resolution helps users select the correct range for the required measurement detail.
