When performing low voltage DC measurements, what special consideration is necessary?

In low voltage DC measurements, the choice of test leads is critical because they play a significant role in ensuring accurate readings. Test leads can introduce resistance and potential errors in the measurement if they are not suitable for low voltage applications. High resistance in test leads can lead to voltage drops, which can distort true voltage measurements, especially when dealing with sensitive electronics or low power circuits.

Additionally, test leads with proper insulation and appropriate gauge can mitigate issues such as noise interference and maintain the integrity of the signal being measured. This makes it essential to select test leads that are specifically designed for low voltage applications, ensuring better connectivity and minimizing measurement errors.

Other factors like the type of multimeter, the measurement environment, and the distance of measurements are important as well, but they do not have the direct, immediate impact on the accuracy and reliability of low voltage measurements as the choice of test leads does.
