Rigol DM3058 vs Siglent SDM 3055 Bench multimeters
« on: October 22, 2016, 05:19:54 AM »
I have searched and didn't find this.

I am looking for a reasonably priced bench multimeter.  Under 500 $US.  Which means a 5.5 digit desktop.
The 2 that I have focused on are the Rigol DM3058  and the Siglent SDM3055.
Yes, I know they're Chinese made, and they're not as good as Fluke, Agilent, etc, etc.

But this is where I am for price and necessity.

Does anyone know of pro's and con's of these models?  Which is better?
I like the fact that the Siglent has trend graphics with a bigger screen.
I like Rigol in general.  I have a scope and power supply made by Rigol.
I find them to be decent for the money.
If someone can help me choose I would be very happy.

This seems like an obvious comparison yet Im very surprised that there are no Youtube videos on this.

How about a used Agilent 6.5 digit DMM? Since the new models came out they are dumping the old models. What is important for you? If accuracy isn't important then you could save a ton of money and go for the Vichy VC8145.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

I have to be honest and admit that the level of accuracy in a 6.5 digit is not necessary for me.
I have some good handhelds but what I want is the convenience of a bench meter for working at my "lab."
Much of the time I work on stuff in the garage or elsewhere so the handheld are good for that.
But I want a bright, easy to read screen with big numbers for lab work.
I like the features of modern bench meters for programming, etc.

Most of all, the work I do really doesnt require that much accuracy.
But since the Siglent and Rigol are basically the same price, I might as well figure out which sucks less :)

Here ^ the Siglent is excellent. I have a SDM3055 as a demo unit and it spends all its time on my bench.

There's a # of threads on the 3055, Siglent have the FW pretty good on them now, I'm not aware of any outstanding problems/bugs with them.
As with any long threads about a product you'd be best advised to read it from the end not the beginning to get a better picture of how they are NOW.

I wouldn't rule out the VC8145 entirely. It has a big display with backlight. This was one of my requirements for a bench meter as well. I do have a Keysight 6.5 digit DMM but I still use the VC8145s (I have 2 of them) the most. I never tried to control the VC8145 over the serial port though. Somebody has reverse engineered the protocol so remote control shouldn't be a problem (see http://www.26th.net/blog/vichy-vici-vc8145-digital-multimeter-rs232-protocol/). One of the things I really like about the VC8145 is instant continuity which is something higher end DMMs have problems with (short delay which is annoying IMHO).

Ive scrolled through hundreds of posts on this section, searching too.
Yet there are far more posts, reviews on the Siglent than the Rigol.
I guess that's a sign.

Ive looked at both models' features and they are pretty close.
I do like the Siglent screen better.  The graphing looks neat but I have a scope.

Surprised Eevblog or Lorton or anyone else hasn't done a video comparison.

If you want to save a few $ there's also the more recently released 4 1/2 digit SDM3045X.
Not quite as much functionality though, compare the datasheets.  ;)
