NanoTronix's
Multi-function cable fault locator (Model No.: NCM-1000)
is an excellent and highly accurate hand-held measuring
instrument to check any problem and distance to
the event on the cable by using 3 different cable
testing methods: MTDR (Metallic Time-Domain Reflectometer),
RFL (Resistance Fault Locator) and Capacitance measurement.
It also provides additional two functions, found
in DMMs (Digital Multi-Meters), measuring DC voltage
and resistance. |

NanoTronix's
Multi-function cable fault locator (Model No.: NCM-1000)
is an excellent and highly accurate portable measuring
instrument to check problem and distance to events on
cable using three testing methods: Metallic Time-Domain
Reflectometer(MTDR), Resistance Fault Locator(RFL) and
Open mode.
It also provides additional three functions, found in
DMMs (Digital Multi-Meters):
DC voltage measurement, resistance measurement and capacitance
measurement.
The MTDR shows the continuity of characteristic impedance
along the cable under test applying electrical pulses,
which is ideal for checking faults (such as complete
open & short, partial open & short, loose connection,
broken lines, loading coil etc.) on any cables which
consist of at least two metallic conductors (such as
telephone lines, power lines, UTP networks, CATV or
CCTV, lines etc.).
The RFL figures out the total length and distance to
the insulation resistance reduction point on clables
with three metallic conductors. It calculates the distance
and insulation resistance with high accuracy via Murray
Loop Testing method.
The Open mode calculates the total length or distance
to an open circuit of extremely long cables up to 100km.
It measures the total capacitance of the
cable under test and converts it to distance based on
the information about capacitance per unit length of
the cable.
NCM-1000 performs all the measurement process automatically
and
displays the results in the graphic and tabular forms
through a color
graphic TFT LCD screen with 640x480 pixel resolution.
The instrument design allows the user to easily determine
the conditions
of the cable being measured.
NCM-1000 is an excellent instrument for the cable installation,
maintenance,
repair after fault finding regardless of the cable installation
environment. |
