| Read those 
		reviews! I love the Internet! It is so easy to get information 
		from others about what is good and bad about any given product now - you 
		use to have to subscribe to Consumer Reports and hope they review your 
		item or know someone else that bought the same product. Nowadays, people 
		are so free to share their opinions online you can learn most everything 
		you need in a few minutes of searching and reading. If you read those reviews, not many people had good 
		things to say about the included software. Few were able to get it to 
		work. When mine arrive, I tried as well and could get it to 
		work once per reboot, and then it wouldn't read any data anymore. This 
		is a shot of the screen: 
		 The digital and analog buttons on the right blank out 
		the upper and lower meter sections. List brings up a list of sampled 
		points, graph brings up a simple graph. I wasn't able to get it to work 
		long enough to try the sample recording functions, so I can't speak to 
		those. I did some poking around and it looks like it was written in 
		Visual Basic 6.0 and not updated for any of the newer operating systems, 
		which likely explains everyone's issues. Plus, it has the standard "COM1" through "COM4" port 
		selections, and often times external serial port devices get pushed 
		above those standard locations. But I really like the visual appearance of the analog 
		meter! But then again, I started playing with electronics back in 1971 
		at the ripe old age of 8. We didn't have digital meters back then. I 
		wouldn't discover computers for another 4 years. Ok, boring 
		backstory - get to the point already! I'm writing my own data logging meter application 
		program for this meter. It will work with other meters that have the 
		same protocol, and I know others exist that do - and can likely be 
		adapted pretty easily for meters with different protocols, but that 
		isn't my first goal. In software engineering, first make it work. Then make 
		it work [better, faster, easier, whizzier, ...] My needs are: Standard CSV / Text that imports into Excel easilyRegular sample period, dynamically adjustable by the GUI
 Ability to record delta-samples VS just doing fixed time intervals
 Auto-adjust to whatever the meter is set to
 Work with modern Windows operating systems - so built in Visual Studio
 32 or 64 bit compatible
 Average multiple samples to smooth out erratic data
 I'm using it right now and have been for a couple of 
		days, and as I use it I'm throwing in functions that make it nicer. For 
		example, I found that while gathering data I was writing in my notebook 
		when I was doing certain things so I could see later in the log file 
		what happened to my experiment and could correlate by timestamp to the 
		event. After about the 5th time, I thought to myself "This is silly - 
		the log file should contain my notes along with the timestamp whenever I 
		want to add a note!" so I stopped, spent 5 minutes, and added that 
		feature. No more paper notes! In another case, I forgot to check my little checkbox to 
		turn logging on and had to re-do a two hour test. So now I'm changing 
		the color of the log file path textbox to be green when you are logging 
		and red when you are not logging - so much more "IN YOUR FACE" than just 
		the little checkbox. In the end, I think I'm going to end up with quite a 
		nice little data logging application. And since others seem to be 
		complaining about the software that comes with the meter, I think others 
		can use it as well. Beta 
		testers anyone? 4/2016: This will be a commercial software product. The 
		beta is over. Next step will be a kickstarter project to fund 
		development of some enhancements that are kind of important before 
		letting it out for public consumption. There is a ton of work that 
		still has to be done - for example, I know that if you are logging to a 
		data file on a remote network share and that share becomes unavailable, 
		the code will crash. Error detection and recovery is often times more 
		coding than the actual main purpose of a software module as there are 
		always more ways things can go wrong than go right. The core 
		functionality is done as I've been using it to record data for
		another project (and article) and 
		I'm throwing this up on the web and will hopefully see it indexed in the 
		next couple of weeks. If you are interested, send me an email and I'll be sure 
		to let you know when the kickstarter goes live. Send me an email request to: dmmlog (at) dascc <dot> com David SoussanChief Engineer, DAS Computer Consultants LTD.
