The Megger TDR500/3 is a hand held, compact Time Domain Reflectometer for locating faults on metallic cables. It has a minimum resolution of 0.1 m and a 5 km maximum range depending on velocity factor selected and cable type.
Four output impedances are available (25, 50, 75, and 100 Ω) and a velocity factor between 0.2 and 0.99 will meet any cable test requirements.
The Megger TDR500 menu allows the units of the distance and velocity factor to be changed. To enter the menu, switch the instrument on holding down the warble key. To change the displayed units, press one of the velocity factor keys. The options available are m and Ratio, m and m/us, ft and Ratio and ft and ft/us.
AUTO selection of gain and pulse width.
Ultra fast pulse for near end fault identification.
Trace HOLD feature.
IP54 rating offers real life working.
Designed for use on all metallic cable pairs.
