| Status on the SDM3045X relay click |
| (1/1) |

What's the status on the relay click issue with the SDM3045X? I mean the annoying click and ~1s delay around 2V (or 2mA for DCA measurement), see e.g. https://www.eevblog.com/forum/testgear/will-this-2v-signal-damage-my-bench-multimeter-over-time/ . Summary of the situation as I understand: * the click can be avoided by using the 60V (or 60mA) manual range, i.e. losing 1 digit of precision. * hacking the firmware to an SDM3055X-E can help (see e.g. https://www.eevblog.com/forum/testgear/looking-for-benchtop-multimeter-cheap-but-good-enough/msg4035127/#msg4035127). Is that right? Is there still hope of a firmware fix from Siglent? Can someone confirm that hacking to SDM3055X-E will fix the click issue? |

Thanks, I see that people successfully upgraded their device to SDM3055X-E but I didn't see a mention of how this affects the click issue. Does it actually solve it? |

Study the thread more and the datasheet range step differences between the 4.5 and 5.5 models. ;) |

Thanks for your patience, I get it now :) |
