Voltage Reference for Digital Multimeters

A voltage reference produces a constant level of voltage over time regardless of load, changes in power supply, or temperature. Voltage references are used in power supplies, analog-to-digital converters, digital-to-analog converters, and many other applications where voltage levels must be maintained at a steady level. Without a voltage reference, precision is greatly affected and may render the device inoperable. Voltage references can vary greatly in performance. A voltage reference for a power supply might hold its output to within only a few percentage points off of its nominal or stated value; however, a voltage reference to instrumentation-level standards are measured in parts per million regarding stability and precision to the nominal or specified value.
