DESCRIPTION
The TDR1000/3P is a hand held, compact Time Domain Reflectometer
for locating faults on metallic cables. It has a minimum resolution
of 0.1 m/0.3 ft and a 5 km/15 kft 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 TDR1000 has a simple selection option which together with a 4
way control switch offers an intuitive operation for the user.
FEATURES AND BENIFITS
An AUTO selection option ensures that the most effective parameters
are selected depending on the range required, aiding rapid diagnosis
of the TDR trace. Dual cursors allow complete flexibility, giving the
operator full control and instant indication of distance between two
points.
A trace HOLD feature also allows comparison between conditions,
something not seen on most other handheld TDRs. Extra high
resolution together with white-light backlight and grey scale tones
give the graphical display a vibrancy, aiding the user in identifying
key events on the trace.
