Megger TDR2050 Time Domain Reflectometer
Includes: Megger TDR2050, Split conductor dual fused test lead set (2 pairs), TDR2000 Series user guide CD, Download kit, Carry case, AC-DC charger, User guide CD, Retractable sheath fused test lead (1 pair).
Designed for the location of faults in electrical power supply cables the Megger TDR2050 is tough. Supplied with fused test leads as standard the are rated to CAT IV 600 V and are dust and weatherproof to IP54, so there are ready to work in the real world.
The TDR2050 features an enhanced and highly intuitive user interface. It is the first instrument in this class to incorporate a built-in 600 V input protection filter suitable for CAT IV 600 V applications. In addition it offers a tagging facility that allows users to add a name - such as circuit ID or building name - to saved traces has also been included.
As a further aid for users, TDR2050 also features an automatic FindEnd function that provides a convenient way of making fast cable length measurements. Unlike competitor products, the TDR2050 has built in protection up to 600 V CAT IV, not an external filter.
The dead zone effect of a standard pulse TDR can mask near-end faults and make them undetectable but the inclusion of a step function on the TDR2050 eliminates this problem. With step TDR technology the signal is injected at full strength and stays there until a disturbance is detected, making the TDR2050 suitable for detecting near end faults that standard pulse TDRs can miss.
