James Posted August 6, 2015 Report Share Posted August 6, 2015 ndb: Yes, the atomizer resistance should not be included in the mod resistance. If it's the only atomizer you use, it doesn't really hurt, but that's a big if...As far as mod resistance goes, honestly it's much better to leave it at zero than to be guessing. A value higher than what is right can destabilize the temperature protection, especially at low power when it's most useful (the dry case).

BryanC84 Posted September 22, 2015 Report Share Posted September 22, 2015 Does anyone know what the mod resistance may be for the hcigar vt200? Link to comment Share on other sites More sharing options...

Droopydroors Posted September 24, 2015 Report Share Posted September 24, 2015 Is it the Raw ohms or the cold ohms that we should use 80% of? Link to comment Share on other sites More sharing options...

Xx3dge Posted October 2, 2015 Report Share Posted October 2, 2015 well my hcigar vt200 shorted with a brass bolt I had a mod resistance of .005 so I put it as .0045 so its 90%. seems like the brass 510 really helps cut down the resistnce. Link to comment Share on other sites More sharing options...
VapingBad Posted October 21, 2015 Report Share Posted October 21, 2015 VapingBad said:I just tried Analysis Atomiser with a Velocity clone with 2.5 sq mm solid copper in place of the coil, the closest thing I could rig to a short, but the atty will have a few milliohm. I got 10 milliohm for my 1590A mod with a VariTube with stretched spring using 14 AWG wire and 13 milliohm for the Evolv mod, I suspect that the common earth rather than the 510 is why it is higher. But I don't think the resistance is that high I need a better method like a brass bolt to fit the 510. 27/7/15 fw I found a better way with just a 6.3 mm copper rod, a copper or brass M7x0.5 bolt would be better and instead of 80% of 0.010 ohm I now get 0.004 ohm reading from that mod, the pic shows 0.005 but twisting it into the thread it goes as low as 0.004 and you should always use the lowest reading. Always set the mod res to 0 before doing this. Link to comment Share on other sites More sharing options...

Dejay Posted October 25, 2015 Report Share Posted October 25, 2015 Amazing feature! I've always wondered about mod resistance affecting temperature. Thanks evolv for making such a well thought out piece of hardware and software! And for this forum - in my opinion this forum is a total success Link to comment Share on other sites More sharing options...
Mdelaere Posted October 27, 2015 Report Share Posted October 27, 2015 I tried it with some copper wire on my velocity deck, it was an extremely snug fit. Mod read like 0.02, that felt really off... might have to try something else. Link to comment Share on other sites More sharing options...
Dejay Posted October 30, 2015 Report Share Posted October 30, 2015 I tested my mod resistance with a thick multistrand wire (don't have a nice copper rod).Raw ohms with Stumpy RDA bridged posts: 0.016 ohmRaw ohms with wire pressed inside the 510: 0.007 ohmI set mod resistance to 0.007 ohm and WOW does it make a world of difference!!! Previously I "tempted out" at about 30 watts with 420°F. Now with 420°F it temps out at about 88W ! So I've previously vaped at much lower real temperatures.

VapingBad Posted November 8, 2015 Report Share Posted November 8, 2015 This has to be the cheapest and easiest if you have a decent soldering iron and an old carto: just solder the positive to the negative then sand through to the brass of the positive, plenty of flux flood the centre at first then run the solder around the centre sealing the gap. As accurate as the solid copper rod and more stable so easier to use, remember to set the mod res to zero before testing! Link to comment Share on other sites More sharing options...

scoopy Posted November 8, 2015 Report Share Posted November 8, 2015 Just wondering because I'm using a varirube with 14 awg in a 3d print and using the grounding ring that came with it.... I wadded up a ball of 14 awg and am getting 0.008......does that seem kinda high or is yours just lower cause the better ring? *edit*I got 0.010 on my evolv reference mod(there new anodised one).....what did u get with your new method on this mod Link to comment Share on other sites More sharing options...

VapingBad Posted November 8, 2015 Report Share Posted November 8, 2015 scoopy said:Read my edit about the reference modI have not tried it and am running battery analyser ATM so cant right now, but got 0.004 with a copper rod, it was originally 0.003 higher than the VT when measured with the Velocity, but the 510 was not tapped through and a board mount screw was missing, once I fixed those it seems about the same. I will test it later and edit this post.ETA the ERM measured 0.004 with both the soldered carto and copper rod methods, I set the mod res to 0.0036 following John's advice and considering that 0.004 could be 0.0035 with rounding.

scoopy Posted November 8, 2015 Report Share Posted November 8, 2015 What do you mean the 510 wasn't tapped through? So your reference mod read 0.004 with the copper rod? With the ball of copper wire I got 0.010 but used 0.008.......mine is the black anodised reference mod (sent my original in for repair and they sent me back a black one!.....Yay!) Where did you get the copper rod and is it solid I'm assuming? Link to comment Share on other sites More sharing options...

Where did you get the copper rod and is it solid I'm assuming? Look at the pic on page 1 you can see it sat proud, I got a plug tap for 4.50GBP from eBay and ran it through and now it sit flush. Yes it measured 0.004, I posted a pic on pg 3, and I didn't have to put as much pressure as with the VT and expect it is a frication lower res. I saw your black one, we are all jealous.I got the copper rod from eBay a while age for another project, I have some a bit thicker that I need to put in the drill and file down so the M70.5 die I just got from China for <2GBP can make a solid copper one.

VapingBad Posted November 9, 2015 Report Share Posted November 9, 2015 scoopy said:Do you mean the 510 wasn't screwed all 4th way down into the box?Yes, the threads were not tapped through, it was tight, but not fully screw in, the top was 3-4 mm higher than it should have been. Quite a lot of aluminium came off when I tapped it fully through. Link to comment Share on other sites More sharing options...
scoopy Posted November 9, 2015 Report Share Posted November 9, 2015 Yea my black reference mods 510 doesn't sit flush neither but my original raw aluminium one did. So screwing that down further gave you less resistance? Link to comment Share on other sites More sharing options...
