| Wrong DMM probes? |

I got these probes from AliExpress: https://www.aliexpress.com/item/2251832820238585.html The black plug fits fine into my UNI-T UT61E, although it doesn't go in as far as the UNI-T probe. But the red plug doesn't mate with the Volts jack at all; it just flops around not making snug contact. It sorta fits the 10A jack, but not very well. *Both* UNI-T probes fit properly in all of the UT61E jacks. Does my UNI-T UT61E use uncommon probe jacks? Or are these AliX probes improperly made? |

Looking on the picture seems you can fit a small flat screwdriver in between the leaves and push them away from each other. I agree this seems to be trash and is the cheapest version of banana plug. |

Other issues with cheap leads can be high resistance and low current capacity. There is a tendency to cheap out and use plated aluminium instead of copper. Given the relatively low cost of decent leads, unless you regularly destroy them it's worth getting some Probemasters or Pomonas, though Simon seems to be out of stock of the Brymen branded Pomonas. Shouldn't cost more than £20-30 shipped in the UK, and will last a lifetime if you take care of them. |
