Application
TDR-420 time-domain reflectometer is designed to detect where faults in met-
al wires are. This product is designed for:
• electrical wholesalers and cable dealers,
• electrical installation companies,
• maintenance personnel at manufacturing plants,
• building personnel.
This device meets the expectations of all those who have to accurately locate
a fault and wire end in either power or telecommunications cables.
Easy readout
The TDR-420 reflectometer is equipped with a readable colour display that, due
to its 320 x 240 pixel resolution, allows the fault location to be indicated even
more accurately.
Integrated Help
In the TDR-420 device a handy help function has been added to facilitate the
interpretation of the result obtained during measurement. Thanks to this func-
tion, a user can quickly determine the type of anomaly that is present in the
cable segment which is being examined, by comparing the displayed reflecto-
gram with typical fault shapes.
Durable and practical casing
In response to the customers needs the TDR-420 has been designed to operate
in difcult environmental conditions. A unique casing with the IP67 ingress
protection rating ensures that the device is both waterproof and dustproof. An
additional advantage is the elastomer coating of the casing that prevents the
device from slipping out of the hands and provides protection if it should be
accidently dropped.
Device capabilities
The SONEL reflectometer is distinguished for its long operating range of up
to 6,000 m, very low margin of error in measurement (in the order of 1%) and
the ability to adjust both the velocity of propagation and the impedance of the
cable which is under investigation. By using two cursors there should be no
problem with determining both the distance to two faults and the distance be-
tween them.
