Megger Intros Handheld TDR

Megger now offers the TDR500/3-CTV, a handheld time domain reflectometer (TDR) designed for CATV service technicians. The new TDR is intended to locate events including bends, crimps, cuts, shorts, opens and water saturation on coaxial cables.

It has a maximum range up to 15,000 feet and a dead zone of 3 feet. It's IP54-rated and designed for both indoor and outdoor test and measurement operation. An auto set-up option helps determine the impedance of the cable under test, sets the unit accordingly and selects the optimum gain and pulse width. Technicians can also manually adjust the unit’s controls. A trace hold feature allows technicians to view a trace later.

The TDR comes with a soft canvas carrying case with a shoulder strap and snap hook to attach to a tool belt, ladder or cable. Other specifications include:

• Resolution up to 1% of range to 4 inches
• Uses 5 AA-type batteries
• Weighs 1.32 pounds
