Hi Guys, I am looking for a second DMM for my lab. I already own a SDM3065 from Siglent, and am quite happy with it. I would like to buy a second DMM, should have at least the functionality of the Siglent, but preferably slightly better. Looking for suggestions and recommendations. I don't mind good used equipment, as long as I can have it calibrated locally ... Many Thanks, ludee |

Take a look at the Keithley 6500, it is not cheap, but you will get a lot of functionality over the Siglent. For a more regular DMM Keysight is not bad, but Siglent mostly copied it, i.e. you do not get much extra. If you want lower spec. meters, there is some other Chinese brands that works, but Siglent is the premium Chinese brand in DMMs (With Rigol a close second). |

Other people have mentioned the Keithley DMM6500 as well. I would consider that one if I needed something more robust than what I have. |

The 6500 can do a lot of stuff that other DMM's can't. Some notes: Its digitizer makes it a oscilloscope (for low frequencies) with very very high precision. Its configuration is second to none, it has a multitude of triggering and other options. It can be programmed (With a real programming language) to do some very advanced stuff. You may not need these options immediately, but it makes the meter much more than just a extra DMM and a very good secondary DMM (It is also a very good primary DMM). I will admit that for regularly measurements I use my Keysights more than the 6500, but for some measurements the Keysights are not really usable and the 6500 is king. My point is that with the 6500 you do not only get a extra DMM, but you get some extra measurement options. How many extra options depends on how much time you want to spend on learning the DMM. The digitzer do not require time, but triggering and programming do. |

I know some rag on Picotest, but you might take a look at their model M3500A (or M3510A if you don't need the resolution). A few threads around, and they mention an excellent and easy-to-use remote interface https://www.eevblog.com/forum/testgear/picotest-m3510a-vs-hpagilent-34401a/ This is the same as Keithley's model 2100. |
