content: On Gwinstek web site it says the DMM Viewer software came free with the GDM-8251A. I bought it used and didn't get any software. They don't appear to have the software on their web site.Does anyone by any chance have the software they could share with me? I'd like to see what sort of data is being sent to the PC from this meter.

content: Try downloading from herehttps://www.gwinstek.com/en-global/products/detail/GDM-8255AAlso IIRC unless you log in, not all of the download options may be shown.EDIT: nope, does not show even when logged in. Also apparently GDM-825xA share the same firmware, so GDM-8255A software should work.

content: This model should be supported by sigrok. A GUI that supports multimeters is called SmuView.

content: Try this link. It is not the GW-Instek DMM Viewer, but is a custom-written program called tsDMM-Viewer. It is in Japanese and English and I haven't tried it yet, but it looks like it might be interesting.https://www.ts-software-jp.net/download/tsdmv1530.zipOtherwise,HKJmight be able to tell you how to add support for your meter to Test Controller or explain why it might not be possible. Test Controller supports your UT61E, so it is worth downloading and trying just for that.

content: Quote from: Perkele on November 23, 2022, 07:47:01 pmDarn it, the Sigrok doesn't run on my Apple Mac Mini M1.I am thinking about getting an older Mac Mini for like $150, just to install MS Windows on it. I can sit it on top of my mini m1, should look nice. I need a PC for all these PC only apps I've been running into in the electronics realm. (I used PC's for years my first being an IBM XT clone.. the first MS Windows I used was Windows 386 back in 1989 or so; switched to Mac back in 2008 -- hackintosh rather.. then bought a legit mac, the mac mini m1, last year.)Quote from: bdunham7 on November 24, 2022, 03:58:07 amYeah I want to try out Test Controller as well.Yeah I didn't see the 8251A meter listed.

content: Quote from: JenniferG on November 24, 2022, 04:16:18 amOh dear! Get a cheap used PC laptop for those apps. I have my decade-plus old laptop just for banging around with this sort of stuff. That setup is also handy when you need to leave it connected or in an odd place while you use your main computer normally.

content: Quote from: bdunham7 on November 24, 2022, 04:30:21 amThat makes sense, vs. changing the HDMI input on my monitor. Would be nice to see both at same time. What do you think about a 2015 or so macbook with bookcamp for windows? I don't know which cheap PC notebook to buy.. I haven't followed PC's in a while. Would be nice to get a decent one for say $150. Lenovo Thinkpad?EDIT: e.g. Just found this i5 Lenovo Thinkpad, 8gb ram, 256gb ssd for $79:https://www.ebay.com/itm/284843129039EDIT #2: seems like a really good deal, Went ahead and bought it, altogether with tax and shipping it was around $100.

content: Quote from: JenniferG on November 24, 2022, 04:46:01 amI don't know the market either, although the one you found looks pretty good. The problem I have is a lot of people beat up their laptops pretty badly while I keep and prefer mine in nice unbroken condition. So my used laptops are all ones that I bought new years and years ago.

content: Quote from: bdunham7 on November 24, 2022, 05:33:47 amThis was a business laptop so hopefully it's not beat up too much; if it does have problems I'll return it. I do notice the keyes are a little glossy here and there but that's expected due to the ABS material used on keyboard.EDIT: oh sweet, if I want to replace the glossy keyed keyboard, it's only $23 for a new for this modelhttps://www.ebay.com/itm/303128388447

content: Here is a picture of TS DMM Viewer running on a Win 11 Thinkpad logging my Tek DMM4050 aka Fluke 8846A. Software supports many DMMs and runs beautifully. Both the analog meter (upper left) or graph can be toggled to full screen, and fonts can be selected.

content: Quote from: ci11 on November 25, 2022, 03:48:30 amThat's sweet! Can't wait for my Thinkpad. It's only TFT not IPS display but for the price it should be good enough. I didn't know the T450 Thinkpads came with IPS option when i bought this TFT one yesterday. What model is your Thinkpad?Ya know I didn't know how popular thinkpads were when I bought it. I just thought it looked nice and looked like it was probably well built. Then I found out how popular they are after I bought it.. right up there with the macbook I guess.

content: Quote from: JenniferG on November 25, 2022, 11:05:53 amIf the seller hasn't shipped your Thinkpad, you can always request a cancellation and look for another one with an IPS screen.Thinkpads have always been built to exceedingly high engineering and ergonomic standards, including passing MIL-spec endurance tests and complying with worldwide ergonomic standards/best practices. In addition, nearly every replaceable part on every Thinkpad ever made can be found on the used market and IBM / Lenovo publishes service manuals for most of them so they can be repaired step-by-step in the field - something IBM started doing in the early 80's. I am a little biased as I worked at IBM for nearly 19 years and even did a tour in the PC division development labs. if you tinker, the Thinkpad / Windows ecosystem is much less frustrating and cost effective.The Thinkpad in the picture is a X61 Tablet circa 2007 which I owned since new. Still working well despite its 1.7GHz processor and SATA I interface.

content: Just out of curiosity. If I use this GDM-8251A say once per day or every other day, does it make sense to just leave it on 24/7 and just press the ON/OFF momentary button to turn only the display off? Or is it better to power it up and have it boot each time? Just wondering which would be less wear and tear on it.

content: Quote from: JenniferG on November 26, 2022, 07:46:44 amI'm pretty sure there is no real long-term advantage to leaving it on all the time, even in standby. One thing I worry about with meters that turn the display 'off' is whether or not they are maintaining power to the VFD filament. If so, then there is continuing wear if it is on. If not, then the VFD would take some time to come on.

content: Quote from: ci11 on November 25, 2022, 03:48:30 amGot my thinkpad a couple days ago. To my surprise the keyboard is in very nice condition, not glossy.. sort of new looking. Case in great shape as well. Screen isn't that great but it works and the entire thing plus win 10 pro license cost me only $100 including tax and shipping.
