| Looking for Benchtop Multimeter - Cheap but good enough |

Hi, At work I want to create a dedicated place only for testing pcbs. Most of the components are "fix", for example: - 4ch scope will be the siglent sds2104xp - 2ch function generator will be the siglent sdg1032x - several 4ch supplies from peaktech But I also want to install some benchtop multimeter, appx 4 pieces. For our purposes, we don´t need 5,6 or even 7 digits ones. But what it measure, you should count on it. So I´m looking for a relative cheap thing, cheap to buy several ones. But good enough to trust its measures and to calibrate it every year. Favorite is this siglent : https://www.welectron.com/Siglent-SDM3045X-Benchtop-Multimeter Question : Are there other meters nearly as this one, but cheaper ? |

Martin, before you make any decision I'd urge you to carefully study this thread: https://www.eevblog.com/forum/testgear/siglent-sdm3045x-enough-is-enough/ |

I recently bought an Owon XDM3041. It works reasonably well, but I've found some issues: -USB interface does not work with the latest version of Windows -Ethernet interface does not work on my network. If I isolate to just the lab PC and the meter it works. Some bit of ethernet traffic causes the meter to lock up and require power cycle. RS232 control works fine. -Thermocouple measurement needs to warm up for 1/2 hr to be accurate. As a bench meter it seems to work fine, but if I was going to do a let of test automation, I'd watch out for the issues with USB and ethernet. I wrote a driver file for Testcontroller, and that works well with serial interface, and an isolated Ethernet interface. I do like the ability to log to a USB stick, and the graphing and stats. Hopefully Owon get the USB and Ethernet issues fixed. I sent them traffic logs of the interface data in both cases, so they should have enough information to fix it. As far as accuracy, the next best thing I have is a Keithley 179A, and it agrees with that within the expected error. I have not sent it for calibration. |
