Which function is NOT typically associated with a digital multi-meter?

A digital multi-meter (DMM) is designed for a variety of electrical testing functions, and understanding these functions is crucial for efficient usage.

High input impedance is typically a feature of digital multi-meters because it allows for accurate voltage measurements without significantly affecting the circuit being tested. This characteristic is particularly important when measuring sensitive electronic components where drawing too much current can lead to incorrect readings.

Automatic polarity identification is another useful functionality that allows the DMM to indicate the positive or negative polarity of the measured voltage. This feature simplifies testing for users, as they do not need to manually switch the leads based on the expected polarity.

Sample and hold circuitry refers to a DMM’s ability to capture and hold a reading momentarily. This is especially useful when dealing with rapidly fluctuating signals, as it allows users to read a stable value rather than a constantly changing one.

In contrast, low impedance is not a typical function associated with digital multi-meters. A low-impedance measuring device can draw significant current from the circuit, which can impact measurements and potentially damage sensitive electronic components. It is often utilized in specific scenarios like continuity testing or when working with specific low-voltage applications, but it does not represent a standard function of the typical DMM. Thus,
