The line impedance is automatically measured by a keystroke, which guarantees precise results. The shortening factor (VF) is adjustable and the integrated cable database allows for adding and storing additional cable types. During a measurement, one or two cursors are available, which means that distances between two events can be easily measured.

In order to compare two different wire pairs, the KE2100 has a freeze function. This makes it easy to compare the visualization of a frozen with an active measurement. In order to be able to recognize and measure even small events, the KE2100 has a high-resolution, grayscale display that is easy to read even in bright sunlight.

Measurement results can be stored in the device and transferred via Bluetooth to a PC/laptop. The supplied management software is used to manage the transferred measurement results and to create measurement logs.
