Description - Communication Cable Fault Tester
This Communication Cable Fault Tester (GAO8B) combines advanced multi-functional automatic communications with portability and ease of use. This tester is widely chosen by technicians to accurately locate faults in the field, for acceptance and maintenance of lines, inspection of cable electrical characteristics and faults such as breakage, misconnection, geothermy, water absorption, and poor insulation.
Basic Functions - Communication Cable Fault Tester
- Integrates the functions of ATDR, ohmmeter, megohmmeter and automatic bridge
- DAGC + DWAR technology for waveform visualization
- 250V high-voltage digital megohmmeter, ohmmeter displays resistance values to 4 digits
- Safe operation under high-voltage conditions
- High-precision rapid automatic bridge can test for points with poor insulation of 50MΩ within 4s
Main Features - Communication Cable Fault Tester
- Unique single screen displays 6 resistance values between the A, B paired lines and concentration line, with timestamps
- CAC technology, 3 testing clamps, only one connection for complete measurement
- Operation time with Internal-installed LG 2Ah Lithium battery is up to 20 hours
- Precision soldering allows for SMT pin distance of only 0.55mm
- Case manufactured by PELICAN USA - good for low temperatures and high resistance
- Intelligent switch-mode power supply and battery charger protect against over-voltage, over-current, short-circuit and power reverse connection (optional).
- Multi-lingual interface and intelligent printing.
