content: Been wanting one for quite some time now. That's the good news.I also was able to use the discount code "5OFF" for a 5% discount. I ordered from here -http://www.tequipment.net/index.htmlThat's the good news.The bad news is, it's on back order, not to ship for 2 weeks and 3 days.

content: LOL - the shipping date came and went. I knew that was going to happen. The shipping date still says Dec 2.That reminds me of the local power company. When the power goes out and you call to report it, they always give an estimated time of restoration of two hours. Then when the power isn't restored, and you call back, they give another estimated time of +2 hours. In other words, the estimate is not based on anything at all, it's merely designed to keep people from calling back every 10 minutes. It could take all day to fix the problem, but you ain't gonna find that out from calling them.Guess I'll call them at the end of the week and see when they really expect to ship it. I'll probably get an estimate much like the power Co. gives out.

content: DM3058 Digital Multimeter Service Guide - Google Snapshot:The Web link and attachment is a Google snapshot (by Google, not me) of the Rigol DM3058 DMM Service Guide when it was on the Internet. This manual is missing a lot of detail due to its being a snapshot (still useful) , and at least you can see what it provides, including a section on Calibration. Knowing that it does exist and the actual name and contents is certainly of some value to us. So we at least now know what we are looking for in terms of Service and Calibration of the DM3058.http://webcache.googleusercontent.com/search?q=cache:FHIQPuYIwS8J:www.rigol.com/prodserv/DM305X/document/%3Fact%3Dview%26itemid%3D319+&cd=2&hl=en&ct=clnk&gl=us&client=firefox-a

Where is it you feel the 179 has better specs?179 - 6000 count 3-1/2 digit largely industrial meterDM3058 - 240,000 count 5-1/5 digit bench meterAs well as raw specs, there's a lot of things bench meters tend to be able to do.- Connectivity options (e.g. LAN), 4-wire measurement, triggering options, etc

content: That kinda stinks. RigolNA is showing the DM3058E as "in stock," but Tequipment only shows them having the DM3068. The problem with ordering from Rigol directly is that you have to pay shipping and don't get the 6% discount.

content: Update - still empty handed.They are so backed up from the ice storm we had they still haven't been able to deliver my meter. It was delayed from Wed to Thurs., from Thurs. to Fri. then Sat when I tracked it, it just said "An Exception Has Occurred - your package has been delayed.Well, WTF - no kidding.Later Sat it was changed to "Deliver by Monday", so I gave up and drove to the UPS delivery center to see if I could get it myself. There were a lot of people there wanting to do the same thing, freaking out because they needed their xmas presents. Unfortunately, I failed to get the meter, as the lady said it was not available to them to get yet.The message on the main UPS site claims they are delivering on Sat. and Sun, but since it's Sun. I guess I'll just wait ONE MORE DAY. Geez. I thought UPS was the world leader in logistics?

content: Quote from: rstoer on December 23, 2013, 02:47:58 pmThanks. It's definitely new - the calibration sheet is from Oct this year. I don't have much to add to any reviews already existing, except to add that the built-in help system isn't of much use - too simplistic to be of any practical use. Another oddity is that the AC cord came with a right angle connector on the end that plugs into the meter. Funny thing is, it doesn't fit well simply because the cord then interferes with the rubber bumper right there at the corner. Hmmm.The DM3058 manual shows an AC cord that is not a right angle but straight. No biggie - I simply swapped it out with another cord I had, and used the right angle on a PS that needed one like that because of where it is sitting on my bench.Also, the manual still suffers from Chinese-tranlationitis, much like many things coming out of that area.However, on the upside the instrument itself is extremely capable and works as advertised. I'm very satisfied with my decision.

I heard through the grapevine that they weren't delayed so much by the ice storm as much as by an Amazon distribution center that was opened in the DFW metroplex, and were slammed by a new influx of xmas packages from it. Still researching that rumor.QuoteLet me play with it for a week or so. Also, look for an order from me this spring for a new O-scope.

content: Has anyone noticed a bug in DC Current measurement under Auto Ranging mode?When in DC Current measurement mode and using auto range, going up in current from 2.3mA to 2.8mA to 3.6mA will result in an infinite relay switching between 2.4mA and 3.5mA.In manual range mode it's OK, but they have shitty hysteresis between ~2.399mA and ~3.499mA when increasing current and using auto range.Keithley PicoAmmeter 6485 has no such problem, and Rigol DM3058e only has this problem for that specific current range switch, other ranges are OK and there is no problem for voltage auto range switching, at least for this specific 2mV to 3mV that I tested.Also they do not allow you to set termination characters for send and receive, instead you have to figure out that for send you need to use "\r\n" and for receive you'll need to catch "\n" only.

It switched at about 2.37 mA going up and not again until I went back down and switched at 2.01 mA.Tried it many times and no infinite relay switching.Just to document the setup I used a 470 ohm resistor so the voltages were in the 0.9 to 1.5 V range.

content: I was using a photodiode illuminated by a LED light source, but the hysterysis on the photodiode current couldn't have been that large, it was an LED with DC current.I think I also remember trying it with a Keithley 6485 subfemto SMU where I fed DC current from 1.9mA in steps of 0.1mA up to 3.5mA. At 2.4mA the relay started banging, and no readings were made because the relay would not stop switching until I hit 3.5mA.My Rigol version is v01.01.00.02.03.01 please post yours.
