VDV Distance Meter. Cable Length Measurement - determines cable length automatically up to 1500 ft. (457.2 m) on most cables with +/- 5% accuracy and +/- 1 ft. (0.3 m). Cable Fault Finder determines if cable run is broken or damaged. Cable Manager measures cable remaining in box or on reel. Also simplifies cable estimating and helps you bill jobs more accurately. Pre-programmed with nominal cable length constants for: RG59 coaxial, RG6 coaxial, RG11 coaxial, CAT3 twisted pair, CAT5e twisted pair and CAT6 twisted pair. ''User mode'' lets the user adjust the capacitance/foot constant based on the cable being tested. Voltage icon indicates a voltage (up to 20 volts AC or DC) is present in cable being tested and will disable unit. Measurements can be switched between metric and imperial units. Other features included: 2.25'' (57 mm) LCD display, auto-power off, low battery indicator and 2 year warranty. Length constant range: 10 to 40pF/ft. (33 to 132pF/meter). Distance Meter includes: 2 alligator clip leads, 1 RJ-style twisted pair plug, 1 coaxial F-connector jack, 1 9V alkaline battery. Battery life: 425 hours active; 4 years standby. Height: 4.9'' (124 mm); Width: 2.7'' (69 mm); Depth: 1.4'' (36 mm).
