XDM1241 Digital Multimeter Tester 10A AC/DC Current and 1000V DC Voltage Tester, Resistance, Frequency, Capacitance, Diode, Continuity, 3.5 inch LCD Bench Multimeter

I only write a review when a product is really good or really bad, and this one is extremely good. I am working with thermocouples and until now I could never afford a meter capable of measuring down to a microVolt (equals 0.03 degree F on thermocouple), but this one does it! Its not perfect, it reads -0.003uV with leads shorted, but thats not much zero error and far better than I expected for the price. And the error is stable, it does not drift so I can hit REL to zero that out for precise readings. The Math button offers MAX/MIN which displays those two plus AVERAGE which I use a lot because such extremely low voltage is noisy, but unfortunately that disables REL. But its easy enough to mentally add 3uV to the average. All other Volt and Amp ranges read 0 with leads shorted so for normal use there is no issue.It was accurate on Ohms, more accurate than any other DMM I have, and my only dislike was >50M-Ohm shows as "overload" which makes you wonder if there's Voltage on the terminals. This is a hi res screen, so why emulate a $10 multimeter, show "overrange". I love that Ohms will autorange with REL on (zeros out lead resistance) and remembers the REL for each function. For example, on Ohms you short your leads and turn on REL, then you switch to AC Volts (REL off) to check that power is off, then back to Ohms to read across a contact REL is turned back on so if its an open contact the lead resistance is subtracted, but if its open it autoranges to 50M-Ohm range so you know its really open.Amps has two input jacks, "10A" and "uA mA". I was impressed that the 500uA range has a resolution of 0.01uA, the amount of current through a 500M-Ohm resistor at 5V!Having read other reviews I had low expectations for the capacitance function, but in autorange it read most caps within 5 seconds. A few took up to 20 seconds but they were very old and I suspect they were leaky so it took longer to charge them initially. Maybe they've improved it in my software, version 4.0.0. I do agree that instead of showing 0.00, they could display "wait" or something while it determines the value.So if you're a hobbyist like me needing an accurate workbench DMM that's not going to break the bank, BUY IT, you won't regret the purchase.

I rated this 4 stars because of the haphazard assembly of mine and the really poor documentation.Mine arrived with the display screen hanging loose inside. Luckily, nothing was damaged. There is no way on earth any shipping or handling caused that. It had to be assembled that way. I disassembled it (you have to remove both large PCB to install the screen in its holders) installed the display screen and it works fine.The meter appears to be quite accurate. I have a voltage and resistance calibration tool that is accurate to .001% and this meter was within that on both.I bought this model in particular because of its ability to resolve voltage down to 1uV and current to 10nA. I have used it for that and can say it is stable and repeatable at those low levels.The quick start guide supplied with it only describes how to use about half the functions. Things like Math and Dual are ignored completely. The Owon web site lists a users manual for the XDM1000 series but it is actually just a copy of the quick start guide. I found the user manual of the XDM2041 does cover these functions (minimally) although the displays must be slightly different...at least it is better than nothing.Other little things. The USB port is actually and RS232 (COM) style port so look for it under COM and LPT on you computer. The software for the desktop seems pretty useless as it is now anyway. It might have been cool 10 years ago. The meter isnt very heavy and is very shallow so you will need to either mount it somehow or hold it with one hand when changing leads or pushing buttons with the other.Otherwise I am happy with it.

This multimeter has been a great addition to my work bench, it does everything I need it to do, and I am able to capture an output on my computer for when I need to share info when teaching my coworkers how to use a multimeter in their daily electronics repair work!

This is a convenient bench top meter and I'm super happy with it replacing my handheld multimeter most of the time. It's way more stable on a desk than your typical multimeter with flip-out stand, and it's great that it plugs in so I don't need to worry about batteries dying or leaking.I don't have a calibrated meter to test against, but the accuracy seemed good enough for my basic hobbyist usage.The screen is nice and easy to read. My only annoyance is that it doesn't remember the sampling speed across power cycles, and I found the Low default to respond too slowly for most measurements.I was happy to find that the rechargeable batteries inside are 18650 cells rather than a custom rectangular pack - see photo.The USB-B interface is a nice addition which allows for serial based SCPI control of the meter - I was able to read basic measurements and change the mode from an attached computer.Overall this was a nice upgrade to my hobby electronics bench!

Nice looking meter, and it's great that it's battery powered. But it has incredibly slow response on the DC volts mode. It takes 3-4 seconds to measure 14V. I thought it wasn't working at first. Using gold plated probe master probes.
