  • EEVblog #151 – Extech Multimeter Canyon Trip

    Posted on March 3rd, 2011 EEVblog 15 comments

    The Extech EX505 multimeter is IP67 rated, that means immersion in 1m of water for 30 minutes.
    Dave only knows one way to test that…

    • I love your test, and the water temp. It was 5deg F this morning…

    • Dave,

      In addition to all these issues you’ve mentioned, there’s one you missed: looks like the big fuse has moved in its socket. I can’t see if there are retainers at the ends of the holders, but if the fuse moves a bit more, it can cause problems with current measurements.

    • I wonder if it would survive the New York Hudson river!

    • Dave, do you know if ExTech fixed the dogy parts of this instrument?

    • Dave,

      I wish I had been there to join you! Rocky Creek and the canyons look other-worldly.

      Hey, thanks for taking our EX505 along for the canyon trip. You dished out quite a lot of abuse! I’m glad to see our own drive-over video offered some inspiration — even taking it to “point break.”

      Aside from the fun of the trip, I know the video editing and production for a shoot like this takes a lot of planning, time and effort. Thanks for the hard work!

      I’m going to ask your viewers to join me in proposing a new Ingress Protection rating:

      IPDJ — Dave Jones Tested

      Thanks again, Dave!

      • Did ExTech changed anything on the design (e.g. the “naked” hand soldered wire bridge) to improve the product after Dave’s videos?

        I am very happy when companies pays attention on user driven communities.

        • @firewalker Without giving away too much to other ‘guests’, I can say, thanks directly to Dave and EEVBlog’s forums, significant improvements are in the pipeline design-wise and QC-wise.

          This applies to issues he raised like PTC proximity and crowding on the board. The naked wire bridge, on the other hand, was a one-off defect that should’ve been rejected (definitely not part of the design).

          Extech has an expansive, multi-phase QC process which we are proud to showcase. So it was disappointing to see that defective unit which spurred a quality investigation specific to that product line. Related to that, see the EX530 he also featured in the review–it’s more representative of the design.

          We take Dave’s input seriously. The next gen RC200 tweezer meter for example, is substantially redesigned board- and body-wise, pretty much in lockstep with the specifics of Dave’s feedback and the discussion on the forums.

          Crowdsourcing might be a cliché overstatement but from an end-user feedback perspective, Dave and the community at EEVBlog have been an invaluable partner to Extech. We’re excited to be a part of the conversation not only in the videos but also in the dialogues that flow from them.

          Sorry, long answer to your question!

          • Thanks you very much for your immediate response.

          • No need to apologize for a long answer, quite the opposite. I think it is great to see when companies take an interest and actively listens to what their customers want and most importantly act on that input.

            • It is certainly a very positive thing to see companies take constructive and critical product feedback and seriously act upon it like Extech have. It’s what separates good companies from the pack.
              And smart companies will know that responding openly like this really helps bolster their reputation.
              I’ve said it before, but well done Extech.

        • As André said, the wire bridge was a one-off, not part of the design at any stage.
          They started to investigate how it slipped through within hours of me tweeting it!
          For some reason I keep ending up with the extreme outliers of the production bell curve for review!

    • I’m just becoming a bit worried about all this spelunking and water-caving with your multimeters. I mean… well…

      Kids could be watching, is all. Sigh.

      Hair could develop on the back of your anodes… and then the (electron) potential blindness too!!

      Wretched debauchery. Ugh. Oh, bother.

    • Great job Dave! And my admiration to the folks at Extech for not only taking this kind of review in stride, but also for setting a great example of how to take your product to the next level based on constructive criticism. Bravo!

    • As far as I am considered ExTech has a new friend.
