The TDR900 is an advanced
instrument capable of measuring cable lengths and finding distance to
an open or a short using Time Domain Reflectometry. It offers
exceptional features and a range capability normally associated with
far more expensive instruments. The measurement range spans from 15ft.
(5m) to 10,000ft. (3km) with a minimum resolution of 20in.
(50cm).
TDR900 can be used for any
cable consisting of at least two insulated metallic elements, one of
which may be the sheath or shield of the cable.
The Meter can be closely
matched to the cable under test using the menu selection keys. The
propogation velocity value can be similarly adjusted to match the
cable under test; thus ensuring an accurate distance measurement. The
other user adjustable setting is changing the distance measurement
units (feet or meters).
The Meter is housed in a
rugged ABS enclosure which is dust and weatherproof to IP 42. The unit
also comes with a soft carrying case and an alligator clip adapter. It
is powered by 4 AA (NEDA 15A or NR 6) batteries, which are stored in a
compartment on the back of the Meter.
