DESCRIPTION
The 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 TDR500/3 has a simple selection option which together with a 4
way control switch offers an intuitive operation for the user.
FEATURES AND BENEFITS
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.
Extra high resolution together with whitelight backlight and grey
scale tones give the graphical display a vibrancy, aiding the user in
identifying key events on the trace.
