I won't make your life easier... ;D Sanwa PC7000 is a good featured option as well - just like the Brymens, it has a 500.000 count mode as well, but it is a bit more accurate. https://www.sanwa-america.com/products/pc7000-digital-multimeter-with-true-rms-and-pc-link I don't have one, but I have used their analog models back in the 1980s and they were excellent meters! |

I have finally seen a nice comparison for the Hioki lineup: https://www.hioki.com/euro-en/download/32992 No wonder the saying "there's no perfect multimeter" keeps coming up... I like the idea of Auto AC/DC, the cute series (422x) have voltage detection (does that mean non-contact? - I guess) The 6223 model looks really cool for generic work. Though it doesn't have diode or capacitor checking - which I guess is no big deal with a second meter geared more towards electronics. My shortlist for Hioki would be: * 6223 * 4253 * 4256 * 4261 * 4282 * 4282 If I can find them and see prices that would be great. I'll check with my local industrial part supplier if they deal with them; they deal with everyone else including Phoenix Contact, ABB, Carlo Gavazzi, Greenlee etc... so fingers crossed. By the way, I can see that some of the models have USB or Bluetooth connectivity. Does anyone know if they would be Linux compatible and what software would work with these guys? I have been running Arch Linux on my desktop/laptop machines for around 15 years and don't want to switch over to anything else in that respect. I did come across this thread: https://www.eevblog.com/forum/chat/multimeter-interface-with-desktop-linux/ so I need to take a closer look at KST Plot and see if there are alternatives in addition |

Of course there may be other software than sigrok available that supports Hioki on Linux. The protocols appear to be fully documented. At least for the 4252 the interface is a simple serial-over-usb interface so you could even roll your own. Brymen also document their protocols. Fluke's protocol documentation for the 187/189 is unofficial (https://photonicsguy.ca/reference/flukemeter). I believe the 287/289 protocol is the same as 187/189. I don't know about Gossen's protocol, but since sigrok supports it there must be something out there (even if only in sigrok's source code). |

Checked out SigRok, it looks interesting. Also found this: https://www.eevblog.com/forum/testgear/program-that-can-log-from-many-multimeters/ many more meters seem to be supported and not just the lower tier ones which seems to be primarily where SigRok is aiming: https://sigrok.org/wiki/Supported_hardware#Multimeters Another piece of good news. I found a local presence for Hioki, but no pricing :( there are two distributors however, outside of RS and Farnell so they maybe able to help with a reseller if they can't sell directly themselves. |

Is it actually on the small side or are the pictures deceiving? --- End quote --- It is small, I can take a pic on monday from it in relation of other meters when I´m at work. --- End quote --- Tuesday... 8) From left to right: Fluke 115, 117, 175, 87V, 289 and my private brymen 869s. |
