Extech EX410A DVM Don't Buy

What does that cost? I got a similar Flir unit (a freebie!) but it's mostly useless. The post on the stand limits how big a board you can image, and it doesn't have an adjustable focus.

The Uni-T 260B handheld thermal imager, with the close-up lens, is great.

I got their 139C dvm too, and it's fine. It reads about 0.2% low. When it times out, push some button and it wakes up.

I blew the current fuse on the Extech, couldn't figure out how to replace it, so I threw it away.

*Very* useful indeed for troubleshooting boards where something's gone short or low-z.

They do make accurate meters. I've had one for about 7 years now and it's a main go-to for everything except very high voltages or energy levels.

That was the right thing to do, John.
