TDR500/3

The TDR500/3 from Megger is a handheld time domain reflectometer. It is a hand held, compact time domain reflectometer for locating faults on metallic cables. It has a minimum resolution of 0.1m and a 5km maximum range depending on velocity factor selected and cable type. Four output impedances are available (25ohm, 50 ohm, 75ohm and 100 ohm) and a velocity factor between 0.2 and 0.99 will meet any cable test requirements. The TDR500/3 has a simple selection option which together with a 4 way control switch offers an intuitive operation for the user. An AUTO selection option ensures that the most effective parameters are selected depending on the range required, aiding rapid diagnosis of the TDR trace. A clear operator controlled cursor allows instant measurement of the distance to the fault. A trace HOLD feature also allows the operator to hold a trace on the screen, something not seen on most other handheld TDRs.
