Time-domain reflectometer CA7027

portable

The Fault Mapper Pro® Model CA7027 is a hand-held graphical TDR Time Domain Reflectometer designed for identifying and locating faults on power and communication cables, given access to one end only. The Fault Mapper Pro® measures cable length and indicates the length and distance to cable faults to a range of 9 to 19,000' (3 to 6000m) on virtually any type of cable. It injects a series of pulses into the cable under test. The velocity at which the pulses travel is determined by the type of cable, which is known as the velocity of propagation (Vp) of the cable. The Velocity of Propagation is adjustable between 1% and 99%, enabling accurate calibration to the cable under test. Specifications Range (@ Vp=70%) - 23, 49, 98, 197, 394, 820, 1640, 3280, 6560, 9850, 19000 ft (manual range control) Accuracy - 1% ± of Range Resolution - Approximately 1% of selected range Minimum Cable Length - 1.5 ft (0.5m) Velocity of Propagation (Vp) - Adjustable from 1 to 99% Output Pulse - 5V (peak to peak) into open circuit Output Impedance - 25, 50, 75, 100Ω (selectable) Scan Rate - 2 scans/second or scan held Display Resolution - 128x64 pixel graphical LCD Backlight - Blue electroluminescent Tone Generator - Oscillating 810 to 1110Hz Tone Receiver/Cable Tracer - Model TR03- Available as an accessory (not included) Voltage Protection - 250VAC Power Source - 4 x 1.5V AA alkaline batteries (included) Auto Power Off - Selectable 1 ,2 ,3, 4 minutes or disabled Dimensions - 6.5 x 3.5 x 1.5” (165 x 90 x 37mm) Weight - 12 oz (350g) Operation Temperature - 14 to 122°F (-10° to 50°C) Storage Temperature - -4 to 158°F (-20 to 70°C) Ingress Protection (IP) Rating - IP54 EMC - EN 61326-1 Safety Compliance - IEC 61010-1, EN 60950
