To measure the length of a cable, a cable length measuring device can be used. There are several types of cable length measuring devices that use different methods to determine length. A mechanical cable length measuring device counts the revolutions of the cable as it is passed through it. An electronic or digital cable length measuring device captures electrical or optical signals to calculate the length and show it on a display. The choice of method depends on various factors, such as the type of cable and desired accuracy.
Other ways to measure or calculate cable lengths include the meter stick, folding ruler or folding rule, a mathematical calculation (diameter of the cable ring * pi (π) * cable rings) or weighing the cable.
With the Aufmaster AM1 cable length measuring device and the free app, you can measure the length of cables without much effort.
