SKU: 0.49210 Category:

Several output impedances (50, 75, 100, 125 Ω) are available in an automatic as well as manual setup and numerous measuring ranges from 0.3 to 14 km are selectable.

The integrated and expandable cable database contains numerous cable variants with the corresponding shortening factor (VF). During a measurement, either one or two cursors are available, making it easy to measure distances between two events.

To freeze a trace and view it in detail or to compare two measurements, the KE2100 has a freeze and overlay function.

The KE2100 has a high-resolution display that is easy to read even in bright sunlight, so that even small events can be easily recognised and measured.

Measurement results can be stored in the unit and transferred via Bluetooth to a PC / laptop via Bluetooth. The free management software is used to manage the transferred measurement results of the internal cable database and to create measurement protocols, as well as for software updates.
