Reichelt says that the diameter is 0.8mm, but this is not the minimum pitch it can be used for. Actually the official datasheet states a 0.45mm pitch as far as I can tell https://cdn-reichelt.de/documents/datenblatt/D100/MS6800-12.pdf |

I tried out the Pomona clips and have pictures here. They're okay for SOIC, they work okay for *some* 0.65mm TSSOPs, but are going to be hopeless for anything finer than that. Most of the "minimum pitch" claims on these clips are uselessly optimistic bordering on straight out made-up. |

It's one thing if they work for a certain pitch and another if they work for two, three or more pins next to each other. Obviously pins directly next to each other are much more problematic that single pins. To measure several pins next to each other, indeed the "wedge" style probes are much better than single grabbers. |

So I ordered four "Challenger" clips at Reichelt for 2.26 € each. To my suprise I got four bags with 10 clips each. I can't imagine that this is anything else but a mistake. Probably I just got 90€ worth of clips. They should last for a while. |
