    fluke 116

    Not sure if my meter is showing its age or what. But twice this year I have missed shorts to ground with my 116 set to ohm/tone. While I know that going of the tone/beep of the meter is not the best practice, but i have been doing it with the same meter for the last 12 years and it has worked well for me. But this year I initially missed a compressor to ground and yesterday a defrost sensor to ground. In both cases, they were high resistance readings, like 300+. So maybe at that high of a resistance the meter does not beep IDK.

    Moral of my post is, look at the actual meter and not just listen for the beep....... It cost me a long walk up the steps to the 3rd floor to reset a breaker, and a 3 amp fuse.

    Beeper on < 20 Ω

    I wouldn't advise to look for grounds that way although it might work sometimes.

    Yeah i know its not best, but hell, 99.99% of the time, one probe on compressor term and other to lineset. steady beep and there is the problem.

    Again, twice this year it got me. First time i just shrugged it off, now, lesson learned.

    The reason it got you twice this year is because you were using the 116 incorrectly. The fact that you've been doing it that way for a long time isn't really the relevant factor.

    You should be using the ohms function for finding shorts to ground.

    Trust me.... I have used a 116 since they came out with it, and before that I used the 16.

    Been doing it wrong my entire career. Who knows where I picked that bad habit up.
    Since I didn't know there was a difference on the meter, I had to look up what the difference was.

    been living a lie the past 12 years and now feel like a dumb dumb. Thanks for the heads up that then made me do some reading, that then lead to some learning!

    I make a point of trying to learn something new every day. Sometimes it's a piano scale...sometimes it is a business dynamic. But, it is always a good move to do it. Good for you for being willing to learn! So many people refuse to improve.

    I read everyday trying to learn something new. I also listen to a lot of podcast on topics about business and leadership again to learn. But I now realize, that I have become very cocky with myself, thinking that I didnt need to reread the basic stuff since it was well, basic. Plus, reading about new stuff like magnetic bearing chillers is way more interesting to read than basic electricity. But seeing as how i use basic electricity everyday, and ill most likely never work on a mag bearing chiller, it is apparent i need to step back a little. AND, I clearly missed things 12 years ago that I should not have, which means i need to brush up on my basic again.

    Im pretty hard headed, so for me, its good to get knocked on my butt every now and then. So im glad you knocked me on my butt this time, bring me back down to where I need to be.

    Nope, me using my meter wrong. timeb just pointed out a very huge flaw i had in my understanding of my functions on my meter, and me believing they were the same.

    But im glad he did, it made me look up the difference, and made me realize what a goon I have been for 12 years. And lucky at that seeing as how i didnt miss more issues......

    Do you mean that showing you the limits of the continuity beeper and the link showing that didn't point that out to you?

    When you used the continuity beeper and got a reading you correctly realized you had a grounded compressor. If you use ohms on that meter and get a reading does it mean you have a grounded compressor?

    I posted the link. It’s what is found when I googled ohm vs continuity. In my head, for whatever reason, thought they were the same. I assumed, tone was a) a lazy way to check ohm (hear beep have ohm reading, no beep OL) and b) the cont function didn’t read as many decimals.

    I assume what happened was at some point someone showed me the tone/beep as a quick way to check for a grounded compressor or whatever it was and I just ran with it. Hell don’t need to look at the screen to see what the reading is just listen fornthe beep. Clearly I was wrong in my understanding of the function.

    A good compressor would read OL in your example and a short to found would read 1-2 if checking to lineset.
