Communication Cable-Fault Tester
SGT-8B Communication Cable-Fault Tester
General:
By adsorbing many high-tech achievements, SGT-8B, as a portable and
multi-functional automatic communication cable-fault tester, is
widely chosen by the line-checking workers to accurately localize
the fault and also applied in the fields of measurement and
acceptance of line engineering and the works of line maintenance
and the checking of electrical characterizes of cable, especially
in the fields of the localization of faults of core wire such as
breakage, misconnection, geothermy, water absorption, and poor
insulation, easy operation and excellent performance of which
enable you to be a cable testing expert.
Key Functions:
— Integrate with the function of ATDR, ohmmeter, megohm meter and
automatic bridge
— The technology of DAGC + DWAR can identify the waveform which
can not be identified visually.
— 250V high-voltage digital megohm meter, ohmmeter displays the
resistance value in 4 bits, with function of body self-protection
under condition of high-voltage. No protection in operation.
— High-precision rapid automatic bridge can test the points with
poor insulation of 50M Ω within 4s.
Major Features:
— Unique single screen displays 6 resistance values between the A,
B paired lines and concentration line, sees the test dates clearly.
— CAC technology, 3 testing clamps, only one connection can do the
whole measuring.
— Max available time of Internal-installed LG 2Ah dilithium is up
to 20hs.
— Welding technology of highest-quality in its field, the distance
between SMT pins is only 0.55mm.
— Case manufactured by PELICAN USA has the advantages of
cold-proof and pressure-proof, intelligent switch-mode power supply
and battery charger have the protection function under conditions
of over-voltage, over-current, short-cut and power reverse
connection (optional).
— Humanization Chinese interface and intelligent printing.
