An oscilloscope plots a graph of an electrical signal. In most applications, the graph shows how the signal changes over time: The vertical (Y) axis represents voltage and the horizontal (X) axis represents time. The intensity or brightness of the display is sometimes called the Z-axis. This simple graph can tell us a lot about a signal.

DC resistance meters are commonly used to evaluate current paths, windings, and contact points characterized by low resistance. The results depend not only on the test object itself but also on the connection configuration, thermal state, inductive characteristics of the windings, and the current injection process.
