EEVblog #151 - Extech Multimeter Canyon Trip

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 wish I had been there to join you! Rocky Creek & the canyons look other-worldly. Thanks for taking our EX505 along for the trip. You dished out a lot of abuse! Glad to see our drive-over video offered inspiration, even to “point break.” I know the video editing & production for a shoot like this takes a lot of planning, time & effort. Thanks for the hard work!

I’m asking your viewers to join me in proposing a new IP rating:
IPDJ: Dave Jones Tested

Thanks again, Dave!
André at Extech Inst.

@Tarkusine Fraid not. Cleaned out and the problem persists. Banana jacks have 4 self wiping contacts anyway.

This video is by far the best MM review ever.... just awesome!!!
thanks Dave

@onlywhenprovoked It's an Edelrid Ultralight, a classic climbing and canyoning helmet. Designed mostly for falling rocks, but still offers decent side impact protection.

Holy crap, everyone's worrying about the meter, but I just kept expecting someone to jump into a rock hidden under water. That's super dangerous, don't do it!

Correct me if I'm wrong, but at around 16:00 the PTC leg seems to be out of its hole and appears to have never have been soldered in there in the first place (no sign of solder on the pad).

@38911bytefree Gossen's waterproof offering is sadly not IP67 rated.

@aardvarkjazz Thanks André. Really enjoyed the trip, and yes the canyons are really "other-wordly" which is impossible to really catch on camera. The meter survived just great, and got even more abuse than was caught on camera. Some of the smacks against the rocks were quite hard!

@errold32 Waterproof Kodak PlaySport. Water gets in the mic and muffles the sound sometimes.

[ryanjhi]

lots of floating measurements going on. one of the best episodes out there.

Awesome video Dave, but for me the star of the show was Rocky Creek - what a beautiful place, very jealous.

I once worked for testsafe Australia and one of my jobs was Ingress protection certification so I can post an expert opinion :). While your tests wouldn't qualify for NATA approval, I would say that your treatment of that meter far exeeds any abuse required in AS60529. It would have been interesting to see if the meter still met the reqirements for IP6X after you ran over it with your car.
Dave, you need to build your own dust chamber :)

The whole manual didn't mention how to calibrate the sensor probe on EX505. Mine is off by 1deg Celcius.

[EEVblog]

Yes, to protect the suit on the rock slides.

@pikuorguk My canyon pack has drainage mesh in the sides, otherwise you'd be trying to stand up with 20kg of extra weight in your pack!

[EEVblog]

@astrowanabe Yes, we drive on the correct side of the road :-P

[exnol]

Although it was amazing to see the review, I was sad because I couldn't get anything other that an EX430 ad that too as a present. And Dave, never even think of doing this with a CRO ;) I might be crying over here!

Dave
When a multimeter says ip 67, should it be waterproof without the test leads and or plugs?
I have a pce itm 20 multimeter/insulation tester made by cem instruments.

[bytefree]

Are you planning to get the Gossem in the next trip .... will it survive ?.
It's unbelievable the abuse that this Extech can handle. For 100 dollars, I would buy it for sure. Thanks for the review.

[onlywhenprovoked]

Forgive my probable ignorance but... those construction style hard hats don't offer much for protection to the back, sides, or front of your head. Is it only to guard against falling rocks, , rather than if you fall?
