crossing my fingers

so when i got into rebuildables and sub-ohming i bought an ohm meter from my local vape shop. cost 20 bucks and it wasn't name brand but i tested it out on all my clearomizers and everything checked out so i figured it was fine. i screwed in my omega rda which i will admit has a very long 510 connection and when i screwed it in, the connection in the ohm meter got pushed down and the little rubber insulator underneath it came out. i was able to jimmy the insulator back in but then the meter would read crazy numbers and give me a different reading every time. i went back to the shop and bought another one. another 20 bucks. same issue. this one I'm able to get a reading if i screw the atty down to just the right position (again i used this method on my clearomizers and everything read what it was supposed to) but when it comes to super subohming (i usually build below .2) i don't trust it. i just ordered a smok omnitester. hopefully this one won't have this same problem. fingers crossed. i have now spent enough on ohm meters to buy a new mod or atty. http://www.e-cigarette-forum.com/forum/images/smilies/mad.png

don't know why the smiley turned into a link haha. it was supposed to be:

Connectors have always been a problem in many ways. Adjustable pins, too long, too short, buggered threads, etc.

When measuring, turn your ohmmeter on first, then while watching the display, screw on your device. Stop tightening when you get a solid reading. You can even slightly unscrew it then tighten it again while watching for a repeatable reading. DON'T overtighten the device, as that pushes the pin down in the connector.

All of the little ohmmeters are made in China, competing for the lowest price. Quality of connectors is probably the last point of attention that any design receives.

You should buy a good quality multimeter if you are building that low.

For your last point: I agree that little ohmmeters made in China compete for the lowest price, lowest Price not just means low quality. You need to find high-quality supplier and choose your best vaping gear.

what new mod is popular now? share yours for my reference. Brand is more important or the made stuff ?

i just ordered a SMOK omnitester. hopefully this one won't have this same problem. fingers crossed. i have now spent enough on ohm meters to buy a new mod or atty. http://www.e-cigarette-forum.com/forum/images/smilies/mad.png

Hopefully the omnitester will be good. Be careful not to screw things together too tight. You only have to go far enough to make electrical contact and that will usually avoid pushing pins in.

I use this calculator for new setups. As long as you enter the data correctly it's pretty accurate. It does not take the place of a ohm meter, I always check resistance of the complete atty after a build to make sure I don't have a short. It's just a double check for me that I use along with my black box ohm meter. If my coil is supposed to be 0.5 ohms and it meters way different I know something's up and I have to check things out.

I checked my cheap DMM against a friends Fluke that was calibrated for his work. When I got the black box meter I checked that with the DMM. Then I bought a much better DMM. It's not a perfect system, but I never go below 0.4 ohms so I have a lot more headroom than you do. I would really invest in a good meter if I were building below 0.2 ohms.
