The Fluke Networks MS2-100 Microscanner2 cable verifier verifies voice/data/video (VDV) cables and multimedia sources on common media types, including RJ11, RJ45, and coax. The meter displays a graphical wiremap, cable length, cable ID, and distance-to-fault. A tone generator produces digital and analog signals to locate cable or wire pairs. Digital mode locates high-grade cabling, including Category 5e, Category 6, and Category 6a in bundles or at switches, patch panels, and wall outlets. Analog mode verifies Category 3 and below voice-grade cabling, coax, security, alarm, and speaker wiring. VDV service detection verifies media services, including powered 10/100/1000 Ethernet switches, plain old telephone services (POTS) voltage and polarity, and Power-over-Ethernet (PoE) voltage and pairs. A backlit LCD is oversized for clear viewing in a variety of lighting levels, and a rubber holster protects the meter in rugged environments. Copper and fiber testers are used by network technicians to troubleshoot, maintain, and optimize performance of copper and fiber optic cabling, hardware connections, and network settings in enterprise networks.

A copper cable tester is a device for troubleshooting, inspecting, and certifying copper network cabling. Devices range from one-button tools for checking connectivity to complex tools for certifying network installations. Three types of testing include verification, to test whether a connection or cable is functioning correctly; qualification, to test a network's ability to support specific speeds and functionality; and certification, to verify whether a network installation meets industry standards. Cabling contractors, installers, and network technicians use copper cable testers to set up and maintain networks within a building or on a campus in corporate, academic, manufacturing, and other enterprise network environments.
Fluke Networks, a division of Fluke Corporation, manufactures tools and software for network deployment, performance management, and troubleshooting. The company, founded in 1992, is headquartered in Everett, WA.

My original review below was written back in 2007, when the Sanyo eneloop first became available
through Amazon.com. Part of my initial estimation about eneloop's self-discharge rate turns out to be inaccurate. Please see my other Amazon spotlight review for updated information.
[Original Review follows]
According to Sanyo, the new eneloop LSD (low self-discharge) NiMH batteries can maintain 85% of its original charge after 1 year of storage. This claim is slightly misleading, because it is based on simulation test at 20 degree C. At higher temperature, the self-discharge rate is likely to be much higher.
I have tested five of those AA cells (details are given in my review for the eneloop 4-pack). The average energy loss is about 26% after less than 6 months of storage, based on manufacturer date codes. This self-discharge rate is about 3 times higher than what Sanyo claimed. However, it is still 6 times lower than that of ordinary NiMH batteries. Therefore I'm in the process of replacing most of my existing rechargeable cells to the Sanyo eneloop.
Thanks to lower self-discharge rate, you'll discover a lot more applications for eneloop cells in your house, such as in clocks and remote controls. Do NOT use those cell in smoke detectors, since their discharge voltage profile is very different from that of alkaline cells. Also, don't use them as emergency flash lights batteries in your car, because the higher temperature during summer time will probably nullify the advantage of LSD.
[Update on Jan 13, 2007]
I have tested six new eneloop AAA cells, dated "2006-06'. The average residue charge is 589mAh, and the freshly charged capacity is 827mAh.Read more ›
I had some doubts how they would perform in the real world - in particular, their peak current capability (which will determine how well they actually work in a digital camera). Turns out - they do better than the regular ones. While my 1600 mAh panasonics gave approx 40 - 50 shots consistently, the same digital camera now gives me approx 100 shots with these eneloops. Suddenly my mom's camera which "ate up battery very quickly" - has become a "great camera" from the battery change. If she's happy, so am I. Incidentally - the amazon price is also very good - you can also try getting the ones with a charger - this eneloop charger charges batteries INDIVIDUALLY. This is critical - no matter which charger you buy - get ones that charge batteries individually and not in pairs. Also remember to always mark your batteries, so you don't mix up charged and discharged batteries when charging them. I've found this to be a common problem with many users.
I use a Canon S2 IS, which goes through batteries like they're going out of style. I had thought the Powerexs would be ideal from what I read in their marketing, but I had some very bad luck with them. Out of the 8 Powerexs, one is now completely dead (as of 4 months ago, will not charge at all), and the remaining ones seem unable to hold a charge at all. Despite my best efforts to "match" them, a set of four will not last me a weekend of shooting (I shoot motorsports racing) without needing to be charged at least 4 times a weekend. Meaning I had to bring a car charger and charge in between races, often missing some races altogether.
Enter the Eneloops - so far, so good. They do seem to hold their charge extremely well, as advertised. I don't run any tests, I simply go by what I see. I charge both sets after finishing up a weekend, and let them sit until the next event. I can pull them out of the case, pop them in my Canon and shoot away, it is not uncommon for me to be able to shoot an entire weekend (2 days of racing) on one set of the Eneloops (although I always bring two sets just in case, that is never a bad idea, hence this 8-pack being such a great deal IMO). The fact that they work so well in such a power-draining application is testament enough for me, I will never go back to Powerex.
The Eneloops charge using my Powerex charger, I think you can use any charger that is made for these NiMh type batteries.
