The adopted data can be averaged multiple times.

Ordinary multimeters use dual-integral AD conversion and only measure a few times per second. What is actually displayed is the average value of the voltage to be measured within one AD conversion cycle.

If you want to keep the display value of the previous cycle after the voltage under test changes, you need to add another circuit. A simpler method is to use a single-chip microcomputer as the display.

Some models of digital multimeters have a maximum value function, which displays the maximum value obtained during the measurement process. After a measurement, you must manually press the button to reset it before starting the next measurement.
