Find Best Price at Amazon"Not a perfect analogy, but the point is that you'll find reviewers of battery testers who say that the tester is defective because it said a battery was no good even when it would still run their clock just fine for months. Or they'll say that a tester is defective because it said a battery was fine, yet it wouldn't run their flashlight. The point here is that with any tester, there will be a questionable zone where your battery may do fine in some uses yet completely fail in others. A tester like the Amprobe that places a simulated load on the battery is more likely to say that a battery is no good when it'll run your clock just fine. A tester with no load like the D-Fantix is more likely to say that a battery is good, even when it won't run your flashlight."

Find Best Price at Amazon"(Note: as of 2015 there are two cheaper lines made by Fluke but I know little about them aside from the fact that they are stripped down a bit.). Basically, you can work on most panel boards / switch gear and anything down stream of them (i.e. - feeders, outlets, hard wired equipment, and anything plugged into them.). CATIV is the only rating higher and it adds service drops to the list as well as underground installations. So basically CATIII is the MINIMUM rating you want on your meter and you can't probe the main drop from the power company. I love the sturdiness of this meter, it a Fluke, so it's the brick crap house of DMMs. The rubber holster offers excellent 5 side protection and it feels good in the hand. Most people fail to realize just how much force 10A can carry; this meter uses a single high quality ceramic HRC fuse and all of the standard additional suppression devices to give the user maximum protection. The case is designed with a deep lip / blast shield as well to protect against debris being blown out the sides in the event of truly catastrophic failure. This is a low impedance voltage test that operates on something close to a 3,ooo Ohm resistance. Flipping to the low impedance mode allows this ghost voltage to “dissipate” and read what's really on the line (which should be less than half a volt on a circuit that’s de-energized.). The resistance on a PCB in electronics circuit can often be much higher than 3,000 Ohms...you could short out that segment of your board by allowing current to flow through the meter as apposed in parallel to it. This is why traditional meters use mega ohm class resistors to test voltage, and most of the time that's fine. So always start out in "normal" volts AC or DC then if ghost voltages are suspect, then switch to the LoZ range. It's a latched system which means you get a positive tone every time a circuit is completed. The "Volt Alert" is a non-contact voltage detector that functions the same as those pen style testers that have been on the market for years. It's nice to test walls for live electrical lines prior to drilling or nailing into them. It features high and low sensitivity modes for different wall thicknesses. However in my opinion the amperage range is quite useful for a general purpose meter and perfectly geared for electricians or homeowners. It's written in 9 languages but it's still simple and easy to understand while at the same time giving the user all the information and data that they could possibly need about this meter. So it drops a digit every factor of 10 up to 600.0 (i.e - 6.000, 60.00, 600.0) Now having said all of that, the accuracy isn't reflected in the screen's numeric resolution. Basically, you look at the reading on the display (we'll imagine measuring against a precision voltage reference of 1.000V) The first step is to add AND subtract half of a percent to get a range (in our example 0.995V & 1.005V) then you add and subtract 2 counts. Honestly for precision testing that could be quite a bit, which is why high accuracy bench top meters costs hundreds or even thousands of dollars, however for general purpose measurments, this is actually is really good accuracy. This would leave my other hand free to hold the meter and push the button. Just mark the price up another 2 bucks and give us a pouch for our meters here Fluke! A set of alligator clips would've been nice, but alas nope... Sold separately. Honestly, I have a few Fluke products and a disappointing lack of accessories is actually a common problem. If you find a Fluke Kit for the meter you're interested in at a reasonable price...GET IT! Sure Fluke has a "market" and therefore a "price" in mind, but they build their units to a "standard" first. At the end of the day, they know that these units have been tested rigorously and "proven" so that when they need quality and survivability, as well as maximum personal protection these meters will perform."
"Best meter I have!"
"It does what it is meant to do."
"Awesome Voltage meter at a really good price."
"I especially like the Lo-Z setting, which pays no attention to the ghost voltage one otherwise sees in mains power (120V 60Hz) because of voltage induced from other lines in the vicinity of those in the circuit your measuring."
"You can't go wrong with Fluke."
"The NCV checker is a great little extra just to quickly check if a panel is really dead."
"I use it to trouble shoot access control and alarm security systems."
Watch in wonder as this battery tester works without batteries! That’s right – it uses voltage from the battery it’s testing to work, and even tests rechargeable batteries. The best thing about this battery organizer might be that it makes it easy to see, sort and select your batteries; no more rooting through that battery drawer. USE THE DETACHABLE BATTERY TESTER: Test your batteries (even rechargeable ones) w/ a tester that never needs a battery – it charges off the batteries you test. The Detachable Battery tester does not require a battery, its powered by the battery that is tested.

Best EMF Meters
Therefore, the Trifield Meter can be scanned rapidly across an area without having to stop at each point to search for the orientation that gives a maximum reading. Can locate wiring in walls (using the 100XE version) and major RF/microwave sources such as leakage from microwave ovens, or the field near cell towers. The TriField Meter will accurately measure EMF pollution from these "hot spots" in your home, office, or work environment so you can take steps for "prudent avoidance": poorly grounded wiring, microwave oven doors, dimmer switches, strong analog RF transmitters, automobiles, TV's & computers, and other electronic equipment. Omni-directional electric and magnetic sensitivity.

Find Best Price at Amazon"The service and integrity of both companies are superb, and so are the products. And I have determined where in our Dodge van the magnetic fields are the lowest so she can sit in relative safety. Some of the cardio machines emit almost no fields, some produce medium magnetic fields, and one an astoundingly strong magnetic field (the Fit Stride 95xi by Life Fitness). The earlier versions of this elliptical cross trainer are fine (the 9500 HR) for her to use, but she dares not get on the newer version. The magnetic field in the rear is astoundingly strong, especially when you are actually on the machine. She thought the hit was from the TVs or the elliptical machine, and so did I; but measurements yesterday determined that the TVs and the elliptical trainer were fine and that the problem was a set of three dimmer switches on the back side of the wall where she was leaning to stretch. So far, the dimmer switches have been the most dangerous thing we have yet encountered. One thing I have learned in measuring various fields is that, even for an engineer (biomedical engineering with a bunch of EE courses), much of this field strength measurement and detection is somewhat counter-intuitive. First, as the description of this product mentions, it is capable of measuring magnetic fields in any plane because it has three separate antennae inside. Thus, it is much simpler to use than one requiring a particular orientation to be effective."
"I avoided the EMF issue for a while, but after reading/listenting to books, lectures and websites on the topic, now was the time to assimilate and mitigate. Every 8-10 seconds, rapid spiking to the top of the meter for 2-3 seconds. Initiate or receive call, spiking for a LONG time. OMG, cell phones are out of control dangerous if this meter means anything."
"I've been told this meter has issues with accuracy for certain frequency."
"This meter seems very accurate, but I returned it because it was too bulky to easily carry with me."
"The two main problems: (1) in most places in my house, it reads twice as high for EMF versus a higher-end digital EMF meter owned by my power company, thus making it look like my house's EMF problem is much worse than it is and (2) it doesn't seem to discriminate between different frequencies of EMF so it registers high EMF both for 60 Hz hum and for higher frequency electrical hash that doesn't seem to bother me. I suppose if I were take this meter's readings at face value, I could rewire my house, install EMF shields, apply EMF paint, and install plug-in EMF filters in an effort to resolve an EMF problem that really isn't a problem, so I'm glad I had the chance to see another EMF meter in action as a sanity check. (The meter does read high EMF in those areas, but it also reads high EMF most everywhere else too.). Just this: the meter's poor accuracy for detecting EMF fields prevented it from showing a stronger EMF field in the vicinity of the miswired light fixture versus other areas of the house. Some time ago, when I had a rep from my electrical utility do an EMF scan using a higher-end meter, he DID detect a higher EMF reading in the vicinity of the light fixture, whereas the Trifield meter showed no difference in reading whether it was near the light fixture or in an entirely different room. UPDATE # 2: I've learned that the Trifield EMF meter sold at this page reads high for EMF because of a feature called "frequency weighting." Since writing the original review and update #1, I've obtained a flat EMF meter (EMI Magnetic field gauss Meter detector MG-2000T Triple Axis Professional use Magnetic Interference from MRI Machines Industrial and Medical Equipment Power Lines Appliances EMF inspections) so I've been comparing it with the Trifield in many areas of my house. Even in the evening, when I get somewhat higher EMF readings than in the daytime, the flat meter reads 1.5 - 2.0 mG which looks a lot better than the 3-4 mG presented by the Trifield. My advice: if you're going to get an EMF meter, steer clear of the frequency-weighted Trifield and invest in a flat EMF meter instead."

"Started having some other problems and a closer inspection found that the damper was not working correctly. As another reviewer mentioned, the replacement is a piece of cake (one set screw and two wire nuts)and it sure beats paying the technician."
"(fail safe) Very much depends on the design and installation of the system but the springs break, the units stick and you have some zones going beyond the temperature setting and other zones failing to meet the temperature setting just because the failed unit is taking all of the heat / cooling."

"The Product works fine and i had actually called A j Perri to see what was the problem and they some how quoted us $ 800 dollars to fix the issue with our Air condition and my son who is Engineer who just graduated last year was able to fix this himself ...Thank you Amazon & also You Tube which some one posted Link how you can fix this with Self and also buy this product at Amazon ...it really worked well and saved us a lot of money. AMAZON YOU MAKE THE WORLD BETTER PLACE **THANK YOU **."
"I was sure our thermostats were wired wrong or that there was a problem with the HVAC system because we were getting forced air from the A/C and furnace in rooms that were not controlled by the thermostat that was on!"
"It would be a well built product if the main gear weren't made of plastic."
