PRO3000F60KIT Filtered Probe & Tone Generator Kit Network Cable Tester 60Hz Signal Interference can be caused by multiple sources (I.e. power cables fans lighting etc.) and can make tracing communication cabling almost impossible. The Pro3000F probe utilizes innovative filter technology to obstruct signal interference to make tracing your cable easier regardless of the work environment. Depending on the region signal interference may be at 60 Hz which is most common in North America The Pro3000F60 which obstructs 60 Hz signals and its harmonics . Technicians can also switch between filtered and unfiltered modes with a simple push of a button. The probe’s loud speaker also allows for use in noisy locations and for tracing cable through drywall wood and other enclosures. The probe also touts an autooff feature that deactivates the probe after 5 minutes to conserve battery life. The Pro3000F Filtered probe becomes even more useful when paired with the Pro3000 Tone Generator. The Pro3000 Tone Generator allows for direct connection to unterminated wire using the angle bed of nails clips or terminated RJtype jacks with the male RJ11 plug. The tone generators strong tone and SmartTone™ technology allows for precise pair identification up to 10 miles (16 km) away. Pro3000 Analog Tone Generator and SmartTone™ Use the SmartTone™ capability of the Pro3000 Tone Generator to identify the right pair. Simply short the selected pair at the near or far end to change the cadence of the tone generated. The tone change you hear through the probe can help you identify the correct wire pair. SmartTone™ provides five distinct tones for exact pair identification. Tone Generator features: SmartTone™ Send tone signal up to 10 miles on most cables Line cord features angled bedofnails clips and a rugged RJ11 plug for direct access to phone and data jacks without adapters External switch allows selection of solid or alternating tone options indicated with solid or flashing LEDs Continuity Testing Line polarity confirmation Pro3000F Filtered Probe features: Innovative filtered probe obstructs signal of 60 Hz or 50 Hz external interference Switch between filtered and unfiltered modes with one button press.
