As printing label at SMD component is norm. :-// --- End quote --- The whole meter is a bit old-school. Not much integration. (which can be a good thing - you get to do exactly what you want instead of having to adapt your thoughts to an off-the-shelf IC). |

Can you see which IC in there has “Hioki” stamped on it? Hard to tell from the pictures. --- End quote --- There is no custom chip in this model ( unless they mean the programmed MCU!) |

I missed the arrows... :palm: :palm: :palm: (not sure why they couldn't have put it vertically between IC22 and the capacitor, but... nothing to see here. Move along.) |
