Awesome! I'd love to hear some abrasive noises through it, like sandpaper or a file on different materials. It's really amazing how much those chains sound like large anchor chains from ships in some videos I've seen.

Super fun to play with a bucket of snall screws and washers. Its hillarious. Also the pezioelectric transducers are about 5x more sensitive than than the magnetostrictive sensor and the amp in the probe head. 🤓❤

Thanks for sharing. I followed this link from your recent Facebook posting in the Vintage Electronic Test Equipment.

Very interesting. Thanks for sharing.

I have one just like this HP but branded "Communications Technology" (which is now defunct, having morphed into Fluke Networks). Same model number and appearance. I'd like to find the manual for it.

I have one at my work that I'm trying to fix, do you know where I could find some disassembly/ repair instructions?

I have a portable one that I’ve been trying to fix but can’t find anything about it, model no. 80019E1
