This ergonomic instrument is ideal for testing communication lines, integrated wiring, line weak systems installation, maintenance and engineering. They are widely used in telephone systems, computer networks and other metal wire lines and other fields.Features• Tone trace the required line among numerous cables, perfect for tracking RJ11, RJ45, cables or other metal wires (via adapter) • It tests the physical connection status of network cables, such as open circuit, short connection, miswire and reverse connection • Use the emitter to test the status of telephone lines, such as judging TIP or PING line and judging whether the telephone line is idle, ringing or off-hook • Highlights for 60V endurable. Users can track low-voltage less than 60V without burnout or damage • Clips allow easy access to individual pairs and RJ11 RJ45 easily connect to telephone jacks—no need for adapters • Use on single conductors, twisted pairs, telephone cable and electrical wiring, a practical tool for service providers in network infrastructure installation, certification, and troubleshooting.SpecificationsTransmitter• Dual Tone frequency: 0.6kHz / 1.3kHz • Max. distance of transmission: 2 kilometers • Max. working current: 30mA • Compatible connectors: RJ11, RJ45 • Max. signal voltage: 8Vp-p • Function display : Led for Wiremap, Tone for trace • Voltage protection: DC 60V • Battery Type: DC9.0V（NEDA 1604/6F22 ) • Dimension(LxWxD): 130*47*35mmReceiver• Tone frequency: 0.6~1.3kHz • The Max. working current: 90mA • Earphone jack: 1 • Battery Type: DC9.0V（NEDA 1604/6F22 ) • Dimension(LxWxD): 180*45*30mmSet Includes1 x Transmitter  1 x Receiver  1 x Cable clips 1 x Telephone cable adaptor 1 x Network cable adaptor 1 x Earphone 1 x User manual  1 x Carry case  SKU: 261 Categories: Cable Testers, Network Tester Brand: AZInstruments
