High performance easy to use, Time Domain Reflectometer for Coaxial testing applications Employs optimized pulsing and sampling, coupled with advanced filtering and signal-processing techniques to ensure clean waveform and easy identification Context-sensitive help screens for all functions Small, portable and lightweight 2. High Bandwidth: Tests more of your system capacity enabling users to pinpoint the faults that can cause micro-reflections which can be damaging to digital transmissions.
Proprietary circuit design and software reduce the noise level so that bumps on the trace represent real faults, not just noise. Events previously difficult or impossible to find, are clearly visible with the TV This means that you can clearly see faults further away. High-resolution performance allows the TV to locate problem components in the customer drop.
The TV uses a pulse width of only 1ns, which means the operator can identify multiple events that are less than 2ft apart. This enables the technician to tell which of two components on a cable is causing the problem, even when they are close together. This is particularly important in troubleshooting drops, because components such as splitters and ground blocks can be closely spaced. Now, instead of meticulously setting up the TDR and then carefully interpreting the meaning of the displayed waveform, you push one button to get a high-resolution, low-noise trace, with the events clearly marked.
This means substantial savings in training time and reduced time to get accurate, repeatable measurements. Long lasting, lightweight Lithium Ion battery.
Drop cable continuity tester - accurate up to 5, feet 1, m. I also spent 10 years in the trades as a carpenter, foreman, and job site supervisor working on multimillion-dollar residential projects. In , I also gutted my year-old farmhouse, which required a whole new electrical system. For more information on non-contact voltage testers, I spoke with someone who uses them every day: Mark Tierney of Tierney Electrical out of Hopkinton, Massachusetts.
Tierney has 20 years of experience and has run his own company since A non-contact voltage tester detects electricity in a wire or outlet, just by getting near it.
Because electrical shocks are unpleasant at best and extremely harmful at worst, this tool is useful for even the lightest electrical work, like troubleshooting a thermostat or installing a dimmer switch. I commonly use one as the first stage of troubleshooting before calling a professional electrician. A non-contact tester can also help map out your existing electrical system. I have yet to live in a house that has had anything close to a properly labeled panel, and if you have an old house or apartment, there is a strong chance that your electrical panel is mislabeled as well.
Once you figure that out, label the breaker, and move on to the next one. Most non-contact testers register only standard voltage. After reading what we could on the subject, we decided that a dual-range voltage tester would be better for the home toolbox. It still works the same for standard voltage, and there is the added benefit of low-voltage detection, which is useful for doorbells, thermostats, some AV equipment, irrigation, and some landscape lighting.
In deciding which models to test, we researched units at Amazon, Home Depot, and Lowes. We also keyed in on reputable manufacturers of electrical tools. From that, we narrowed our list down to seven.
We ran a few tests to determine the overall usefulness and sensitivity of each tester. First, I shut off a single breaker at my electrical box and tried to discover which of the 35 wires coming out of it was the dead one. After that, I took a dead wire and saw how close I could get the tool to a live wire and still have the tester read negative. In addition to those structured tests, I used the testers as I wired some outlets, and installed some dimmer switches, a cooktop, a ceiling fan, and a few pendant lights.
After researching the topic, talking to an electrician, and spending hours testing seven leading models, we recommend the Klein NCVT It is also compatible with tamper-resistant outlets, now required by code. Most of all, the NCVT-3 is very easy to use. Most testers detect only standard voltage.
Unlike most other dual-range models, it switches between the ranges automatically without the use of a fussy sensitivity dial. A low voltage detection lights up the lower two orange lights and standard voltage lights up one or more of the upper three red lights. Many companies sell separate high- and low-voltage detectors, but for the non-specialist, it makes sense to have them in a single tool, particularly if it works as easily as the Klein.
The NCVT-3 also has a very durable feel to it. In addition, the buttons are all sealed and the cap of the battery compartment is gasketed, so the NCVT-3 can handle a little rain and dampness.
For battery life, Klein says that the two AAA batteries will provide 15 hours of continuous tester use and six hours of continuous flashlight use. Pick one up. Most of the negatives at Amazon are from people who like the tool but are disappointed that it cannot be inserted into an outlet. As we described above, this is not an issue because it can still detect the current, only displaying it as low voltage and making it compatible with code-required tamper-resistant outlets.
The NCVT-3 is unique because it cannot be inserted into an outlet. At first glance, this may seem like a problem, seeing as most other non-contact testers read power from an outlet only by being inserted into one of the openings. The reality is that because it can read low voltage, the NCVT-3 can still pick up the current from the outside of the outlet, which is essential when dealing with the tamper-resistant outlets now required by electrical code.
It also makes an incredibly loud beep no mute option. This could be beneficial on a noisy job site, but after I spent 45 minutes checking wires in my basement, the volume was enough to drive me a little nutty.
