I've got parcel from Aliexpress today, everything is OK. Any advise on lithium battery upgrade? I'm sic of leaky AAA's. |

Hi, I too had been thinking about rechargables. My idea was micro USB or USB C, then a Li-Ion charger (with protection), a single cell, over discharge protection, a 5 Volt boost converter (maybe the same chip as the charger), and a 5 V to 3.3 V DC-DC isolator / converter which will keep the USB side isolated from any high voltages on the probes. This is the sort of DC-DC I'm thinking of: https://au.rs-online.com/web/p/isolated-dc-dc-converters/1675944/ although there are many to choose from. A home-brew, transformer based, SMPS taking 2.8 to 4.5 Volts in and delivering 3.1 Volts out shouldn't be hard - it's just outside my skill set. Brian. |

Hi. I was thinking more in terms of this ( https://www.eevblog.com/forum/testgear/a-look-at-the-uni-t-ut210e/?action=dlattach;attach=555647;image ). |

I have a question, not technical, but question nevertheless: I've got a broken zip on the case(bag thing), how to fix it? Aliexpress seller doesn't respond. |

Re: zipper - you just need to run it all the way back, at the start, forcefully. You might need to deform it a bit to get it there, and press it back. If you do it too much, you will break the zipper head. Demagnetizing: I've received the cheap Amazon demagnetizer today and tested it: it makes short work of any magnetized tools, so I can highly recommend it. My drill thingie was not even half as effective as this gadget. On the UT-210, I have a -0.170mA offset after many demagnetizing tries, which probably means that's the true zero. For ~8$ seems like a must-have tool around the shop. It gets hot after using it for a while, even in pulses. |
