Fluke Networks 42801004 TS42DLX Telephone Test Set with 346A Plug

The Fluke Networks TS42 telephone test set, available with various line cord connectors to suit specific applications, detects dial tone and polarity; places and receives calls; indicates line voltage and low loop current; has a one-way speaker for hands-free listening and a two-way speakerphone for hands-free conversation during testing; monitors lines without disrupting service; and stores up to ten 23-digit telephone numbers which can be speed-dialed via the keypad. It provides tone or pulse operation. The test set has two basic modes of operation: talk mode for off-hook operations including verifying dialing and receiving calls, and monitor mode for on-hook operations including checking for an idle line, listening for line noise, and measuring DC voltage on the line. In monitor mode, the test set provides high-impedance monitoring of lines without disrupting service. This test set passes a 20-foot (6 m) drop test and has a waterproof case that exceeds American Military Specification MIL-STD-810E. The keypad has 12 standard dialing keys including star and pound, and function keys to store, recall, and redial numbers and to pause for accessing a second dial tone when dialing through a PBX (private branch exchange), among other functions. LEDs on the unit indicate line polarity when off hook, normal or low (below 23 mA) loop current, five different ranges of voltage detected, mute, and battery status. At a voltage greater than 140 VDC, the test set locks out and will not allow off-hook operation. The current LED flashes for 5 seconds to indicate a reading below 23 mA and remains solid for normal readings. The test set is made of high-impact plastic. A spring-loaded belt clip at the base of the unit provides a secure hold on belt loops and D-rings. Additional specifications include various environmental operating conditions. Telephone test sets, also called butt sets, are used by telecom technicians to troubleshoot and maintain copper-wire voice-subscriber lines.

Tone generator and probe sets, also called toners, are used to locate, trace, and isolate cables in copper media networks. Telephone test sets, also called butt sets, are specialized telephones that connect to telephone lines to check for proper operation and to isolate trouble. Some test sets incorporate a TDR (time-domain reflectometer) and toner for determining cable length and locating faults. While certain devices may be used on live networks, others are only suitable for inactive networks. Field technicians and installers use these devices to set up, maintain, and troubleshoot datacom and telecom cabling within a building or in outside plant (OSP) applications.Fluke Networks manufactures tools for network infrastructure installation, testing, certification, and troubleshooting, in copper, fiber, and wireless networks, with its tools widely used by contractors, enterprises, and communication service providers. The company, which operates globally, is based in Everett, WA.What's in the Box?Fluke Networks TS42 telephone test setTests leads with 346A Plug9V batteryInstructions
