Hey EEVblog, I worked for REI for several years on their more modern products. Very interesting seeing you play around with an old CPM. I think the CPM was one of the first products the owner and founder of the company helped to develop. The CPM was just a broadband receiver, which may not be as useful as a spectrum analyzer in today's world with electronics everywhere, but there were still a lot of customers for the CPM up until just a few years ago. It looks like the CPM has been discontinued.

Thumbs up for the 121GW Multimeter!

Now ... teach us how to build one of these with an Arduino, a paperclip, and some gum!

I really appreciate the honesty in these repair blogs. It would be easy to edit out the first 11 minutes of the video and start with your discovery to make yourself seem super-human and magically able to notice subtle things. But this goes far more in line with what I experience when troubleshooting - a lot of time investigating nothing, and then an "aha!" moment with something you thought was unrelated.

It's a licensing issue, you need to connect it to the Internet so it can check you have a valid license to use the probe.

love your repair videos! really shows the best way to diagnose issues in unknown devices

[@rabidbigdog]

One of your best Dave. Thank you.

[@xanderlander8989]

I do enjoy these repair videos, you share your approach and reasoning, as well as the process itself. Resistors do drift over time, so it could've been just out of spec.

That multimeter model number is awful suspicious considering Dave's affinity for Back To The Future ;)

THE EEVBLOG METER!!!!!!!!!!!!

[@ccish8098]

Not to familiar with REI products, but when we used to decom our old scanners / sensors we would change random components to render the device unusable upon purchase but still usable after repair. :)

[@TheManLab7]

Loving the new meter 😂👍🏻
