Style: INDUSTRIAL TRUE RMS HEAVY DUTY MULTIMETER
It's a great meter.Its robust, accurate ,and well,it's a Fluke. I dont entirely agree that it's the same exact meter as the typical iconic 87 version 5. **update There was a glitch in v the meter so I returned it. I will explain... It behaves differently than the non max 87v.It is a little slower on start up and some functions behave slower.From what I can find it is because of the battery difference. The 87v operates on a nine volt battery. The max version runs on three AA batteries. I can't explain the science behind it but I would assume it's because voltage is a little less than 9 volts..(4.5 is what it ends up being versus 9 volts).On diode test it doesn't light up diodes as bright as the normal 87v. Regardless, other than being a tad slower,it definitely a rugged,accurate tough meter. Backed by a lifetime warranty .

Very high quality meter. Though much larger than most meters on the market but very accurate and reliable.

To fairly judge Digital Multi-Meters (DMMs), I must cite a few critical details. Most DMMs are based around an ASIC (Application Specific Integrated Circuit) that neatly packs the basic functions of a DMM on a single silicon die, or, more succinctly, a DMM ASIC. For extreme reliability and durability in mission-critical applications, in the harshest environments (think military), it can be advantageous to sacrifice some accuracy. This is the single instance in which ASIC-based DMMs may be desirable. In the ASIC-DMM design, potentiometers (trim pots) connected to pins on the DMM ASIC, for calibration. An A/D conveter translates the internal reading in the DMM ASIC to a digital readout. Current is measured across a shunt resistor (a very low, precisely known resistance element). By calculating the voltage drop across the shunt, the current can be determined by: V/IR=1 (Voltage/current*resistance)=1. Specific constants are hard-coded into a DMM ASIC. The device also must contain a PMIE precision voltage reference for the A/D converter. The more accurate the PMIE voltage reference, the more relevant counts (digits) the meter can have, and the higher the legitimate accuracy. Many meters omit accuracy specs, duping buyers into believing these DMMs are as accurate as their resolutions (smallest measurable quantity given the number of digits) suggest. For instance, a 20,000 count DMM can measure down to 0.0001VDC, giving it up to 100uV (microvolt) resolution on the 10VDC scale. On the 100mVDC (millivolt) scale, it could measure down to 0.01mVDC, or 10uV resolution. In order for those readings to be meaningful to the rightmost digit (least significant digit), the meter must be accurate to +-0.01%. Anything greater than 0.01% is not exploiting the full resolution of the device, and the resolution is therefore superflous! Maximum accuracy is nearly always found on the DC Voltage function, unless there is also a frequency function (Hz). For instance, a meter with +-1.0% accuracy and 100uV resolution would produce meaningless values for the last two digits, because the error is greater than those. Such a meter would have an error of +-10mV, or 100x greater than the resolution alone would suggest. I might interject, the 87-V MAX has a 20,000 count display if you hold down the the backlight button. The whole idea of using DMM ASICs is offensive to discriminating users for three reasons: 1). 'Linearity' says the meter that is accurate at 10V will also be accurate at 1.0V and 0.1V, that is, it's response is linear across the range, and across ranges. An IC can not produce good linearity, because ICs themselves are nonlinear devices. Higher-accuracy meters take a different route. Rather than use potentiometers connected to a DMM ASIC for calibration, the Fluke 87-V MAX stores digital values as calibration constants revised during calibration. The calibration tech inputs into the DMM the precise output value of the reference used for calibration. It also reads the reference using its existing calibration constants. It says, OK, the reading I'm making right now should be equal to the value the technician entered into me for this calibration step. It stores a digital representation of the relationship between the value keyed in manually by the tech and the reading it took internally based on the existing calibration constants. These digital representations become the revised constants, and are stored in an onboard prom (programmable read-only memory) module, another type of IC. After calibration, all calibration points are stored as a digital representation of the relationship between the value the technician keyed into the meter at each step, and the value the DMM measured internally based on the old constants. For instance, I have access to an eletrical calibration lab with a Fluke 732B DC Standard. Its output is known to within +-0.00000015VDC, OR 0.15uV. If I calibrate my 87-V MAX meter, I put the meter in calibration mode, and it asks for a series of references, one at a time. For the 10VDC step, I connect the 732B, input the known output value, and perform that step. The meter knows two things: 1). what the output value of the standard is, 2). what 'its' reading is of the same standard. It compares those and makes a digital representation to store in the 'calibration constants' memory in the memory prom. Now the DMM 'knows' what to display given an unknown input. The another objection to an ASIC-based DMM is aging of the ASIC. Aging causes measurement values to change over time, a lot! Calibration by using potentiometers to change the output values of the DMM ASIC + basic non-linearity of ICs + excessive long-term drift = an inaccurate meter that will be in constant need of calibration, and will have different accuracy specs at different measurement values! Quality meters also employ isolation between the inner and outer sections of the meter. The analog sensors on the outer board (incoming signal from the meter terminals) can iterfere with the inner board, where the measurement is processed for digital output to the display. Fluke has been known to use optical couplers with digital lasers to communcate from the outer to inner boards, effectively eliminating all electrical interference, and reducing internal noise to the minimum possible. You can check internal noise by shorting the Volt-Ohm and Common terminals, and setting the meter to DCV. It should read zero. Fluke cherry picks the PMIE precision voltate reference ICs used in the 87-V MAX, selecting only the most precise examples! These are aged, which minimizes long-term drift out of the box. That means accuracy is improved, and the improved accuracy is long term. All of the above is not to mention that the unit I received came with TL175 soft, flexible, retractable leads, alligator clips that screw onto the leads, a thermocouple for temperature, and terminal caps to make the unit IP67, sealed against water. The instruction manual is enough to begin using the meter. I read some of the other reviews. Packaging a full instruction manual with each DMM, and simply printing them in sixteen languages, for each nation Fluke markets them in, negates the benefit of revising the documentation when critical information may be discovered after manufacture. I cannot carry 100 manuals everywhere. And I can't search paper manuals by keyword. However, I can fit 10,000 manuals in my phone, and in a single step, search through all 10,000 of them for a keyword or phrase. I also observed a desire for better leads packaged with the 87-V MAX. I have boxes full of every kind of test lead imaginable, and I would have no idea where to buy better leads than what came with the meter. One interesting note, certain DC motors convert the DC input to AC using a small inverter, because speed control is easier, and the phase can be shifted, which has several possible advantages. Most meters cannot properly read current draw when set on DC (the motors have DC input), if the motor is actually using AC. I read the digital readout on the DC power supply I was using. It made no sense. Then I tried a $8.99 Chinese special DMM. That was even worse, all because I didn't want to walk out to my truck, and get my 87-V MAX. The 87-V MAX correctly measured the current draw. I base that on the the motor's label. If I used motors that had the wrong specs, I could burn out the drive circuit, turning a 20 minute job into a three-day affair waiting for parts! The display 'IS' bright, clear, large and easy to read. But the view angle is narrower than some meters. In other words, you should read it straight on, not at an angle. Of note is that Fluke did not bother obtaining FCC approval for use in residential-zoned areas. The FCC residential standard for radio-frequency emissions is more stringent than commercial and/or industrial standards. Consequently, warranty claims regarding readings performed in residential-zoned areas, such as homes, 'may' be questioned. Use the product only as approved. Since the the 87-V uses at least one microprocessor, it produces radiation in the radio-frequency range. The unit is very tough. It can withstand being dropped from 13 feet onto concrete four times, on any side. The batteries last up to 800 hours without the backlight. But how realistic is that!? I use it for diagnostics and troubleshooting. One of our PCs failed. It took me 1.5 hour to repair (replace 3 caps on mobo) using only a PSU checker and the Fluke 87-V MAX for diagnosis. The capacitance function is very hearty, and, as is intuitively predictable, you connect the negative then the positive on polar caps (electrlytic and polymer). Since one reading requires only 250ms, or 1/4 or 0.25 seconds, most transcients can be easily caught, for instance those caused by large inverters. I've had this meter for about three years. Already it has saved me 150 hours over using a $50.00 DMM. Many buyers are sticking with the 87-V, either because they aren't aware of the new 'MAX' model, or for the same reasons some people insist on vinyl records and film cameras. I'm not a instrument-manufacturer evangelist. Give me any quality instrument, and I'll get the job done. But Fluke Corporation obviously put serious thought into their remake of the iconic 87-V handheld DMM--the most popular handheld DMM ever made. I've used both the '87-V' and the '87-V MAX'. Newer isn't always better. But in this case it is. If you don't know 'why' you need this DMM, you don't. But if you do, the 87-V MAX is a safe bet.

You can't go wrong with Fluke. They cost more, but the quality is very good, accuracy is on spot, and they will last several years. I have used various models at various jobs over the past 50 years. They are what the "pros" use and they always deliver.

Excellent quality, lots of features. Accuracy appears to be perfect, compared to by 0.04% reference. Be aware that this meter is huge, considerably larger than my other Fluke meters. This is mostly because of the extra rubber padding so it can meet the drop test requirements.

Giving it 4 stars because the battery situation is a joke. Three AA batteries that sit in a squared cutout on back. Six machine screws to remove & a "tab" to work out towards the bottom of the meter, just to take the cover off. 1 battery has both terminals holding it in place. The other 2 kind of sit in place with two contacts on the meter & two contacts on the cover! You have to align them as you put the cover on. With the cover off you can access the rubber & plastic fuse cover where the cover "tab" is. They should give the case designer a raise for this idea. Also, on startup the meter displays F87 for the model # & the High Voltage Present lightning bolt. I almost returned it because I thought it was broken but I have seen other Fluke DMMs do this, so I think it's normal. 87V Max is 1/2" bigger all around than an 87V & a little heavier. You get excellent leads & alligator clips, (TL-175 & AC-175) a thermocouple, Amp jack plugs & screw on banana jacks for other push on accessories, No instructions, a safety guide, quick start guide & a China leaflet. Online user guide hints about High voltage present symbol but doesn't say it's on at startup. They should revise the user guide. The other thing I don't like is the jack placement. With 4 jacks across the bottom instead of this 2 + 2 design you could wrap up your leads evenly around the meter. I'll probably update this review after I use it more, but the stupid battery design 4 stars is staying.
