GreenleeDM-510A True RMS Professional Plant Digital Multimeter, Green

Great size, good price, solid build quality, accurate, and easy access to (2xAAA) batteries and fuses after you remove one screw. The leads are nice and soft "silicone" instead of cheap PVC and the gold plated probes are nice and sharp.Update: It's still a great little meter a year later. It would be a better buy at the price it was a year ago. $135 shipped. You can get the OEM version for that price still.

Broke after only 3 uses(all low voltage and current dc) and Greenlee won't honor their warranty. Avoid!

This is meter does just about everything, and the size is great too. I first bought the 830A, which is super meter but it was *huge*. This meter has almost all the same functions (no conductivity, no Dbm) and it's *way* smaller.I would say that these Greenlee meters have way more value than Fluke, but it's more than that... Fluke doesn't even *make* one meter with all these features, so this was my only choice.I love it.

This meter is really good, except for 1 major flaw that made me return it. There are also a couple minor annoyances that are not show stoppers, but not good in my opinion.DCV and ACVThis meter has excellent accuracy and is a True RMS meter. It also has a high number of counts for a very good precision reading.ContinuityThe continuity test is so so. It is very fast response, but is not latching. Has a scratchy sound to it, which I don't like. In general you can live with it since it is very high speed, but a latching beep would have made it aces.BacklightThe meter has a really nice backlight. Only issue for me is that when you shut off the backlight, it stays on only for 30 seconds. Not cool. When I turn on the backlight, I want the backlight to stay on until I shut it off.Rec function (aka Min Max)The record function is good, but lacks a "Fast min/max" mode for high speed transient detection.Diode TestChecks standard diodes fine, but can't test even a red LED. This is a show stopper to me. The meter only outputs 1.5V for the diode check, so it can't forward bias even a standard Red LED with a 1.6 forward voltage. My bremen 869 puts out 3V, and the fluke can even forward bias a white LED. A 1.5V diode test is inexcusable these days. Even my 25 year old Fluke 29 puts out 2.9V on the diode test function.Hold FunctionThe hold function is just OK. when you have a value on the screen and hit hold, it will lock the value into the display. This is ok, but not nearly as useful as the fluke AutoHold feature. AutoHold lets you set it, then take your measurement, and the meter will automatically hold the reading for you. For instance, if you hit autoHold, then measure the resistance of a resistor, you will hear a beep and the meter will have locked in the value of the resistor. This is a very handy feature, and one that a Vanilla hold really misses.Overall this is an excellent meter, that is built well, will be safe to use even at mains voltages (CAT iV rated). Brymen is the OEM of this meter which is sold as the BM-257. It is a good meter that will last a long time. Just don't rely on it for LED testing.

I have an old DM-200 and I have dropped it tens of times and it still works perfectly. I bought the DM-510a because it has true RMS voltage measurement, temperature, and capacitance measurements. With the optional cable, you can hook it up to a PC for logging. This unit is quick and as accurate as any portable DMM on market. It's every bit as good as the Fluke meters we have and costs less with a lifetime warranty. Fluke used to be made in the U.S., but not anymore. Most of their meters are made in China, with a couple of exceptions.

This is a very nice meter that is built to last. UL listed for safety and will do the same job as a Fluke for less money. This meter is made by Brymen for Greenlee. Its Brymen model 257. Tons of good reviews online. If you don't have the money for a Fluke then get this one.

Have had many multimeters over the years. This is the first one that has broken. Less than 2 years old and started throwing a calibration error. Called ITM andwas informed it was not covered and needed to be recalibrated at the cost of 160$ so basically junk without support throw it away. Save your money buy the yellow meter. Will never purchase anything greenlee again. Let's be honest it's the budget fluke. Garbage, no support, do not buy.

I bought this meter specifically for it's computer interface capability. Nothing in the literature indicated that the software or cable were optional, didn't find out about this until after I received the meter. The software/cable (DMSC-2U) price is over $88 from Newark, the least expensive source I found. Almost as much as the meter itself. Shame on you, Greenlee. The software/cable price alone is more than I paid for a Uni-T UT60a, which comes with the software (which is also downloadable from their web site) and the cable. Yes, the Greenlee is a better meter, with more bells and whistles, but all I needed was a meter that could interface DC, AC, and ohms to a PC. If the software/cable is optional it should be stated so in the ad. Deceptive advertising, intentional or not. If not for the software/cable problem I would have rated it a 4 star.
