The KF10 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 cables with three metallic conductors.
It calculates the distance and insulation
resistance with high accuracy. 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. The KF10 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 is
designed to make the user determine easily the
conditions of the cable being measured. The KF10
is an excellent instrument for the cable
installation, maintenance, repair after fault
finding regardless of the cable installation
environment. |
