Killed new multimeter?

Post by inforoo »

I just bought this multimeter: https://www.adafruit.com/product/2034

It stopped working. I replaced fuse the and battery but no dice. It's always showing out of range.

Any ideas? Is it possible to exchange it?

What were you doing with the multimeter when it "stopped working"?

Testing circuit continuity on a protoboard I had soldered.

What are you connecting the leads in and what setting of the dials?

Pics of the board below. Notably it was not powered nor was the bolt IOT board connected when the meter began to fail.

Yes, my poor soldering skills. That was a couple days before I went to check all those solders with the multimeter though.

The continuity setting is actually for a rough check of the "breakover voltage" for diodes.

It's better to use the "ohms" setting if you are checking that your soldering/wiring is correct.

Lots of people like getting the "beep", but it can give you a false sense of security if you're really concerned with a low resistance connection.
