EX330 multimeter sometimes don't measure resistance

by superrune on Fri Apr 07, 2017 8:50 am

I just got an EX330 multimeter from the Adafruit store. When I measure resistance, it is sometimes stuck at 0L. If I wriggle the contact in the rightmost plug, it starts measuring and it stays OK - until I take out and insert the cable again. Then I have to do more wriggling. I noticed the rightmost plug feels a little loose, I can move the plug in and out a bit, while the middle one sits really well.

Its my first multimeter, and I'm not sure if this is normal. I hope someone here can give me an answer.

Hmmm. Don't have my EX330 in front of me right now. I forget what the banana plugs look like. Are they springy? Maybe gently pry the sections apart a bit to get a tighter fit?

Can't see any banana connectors on this. The connection to the body of the multimeter is more cylindrical. It's only the connection to the body that I'm looking at, by the way.

OK, looking at one now. Yeah - there's no way to get in there to adjust the contacts.
Please email support@adafruit.com with a link to this post for a replacement meter
