Tank Jumping on APVs

[Frenchfry1942]

Just curious; I have an RTA on a mod and it tasted a touch warm for the settings. The kanthal coil is 1.1 ohms at 13 watts/3.9 volts. I switched it to another APV and it wasn't as warm, close, but noticeable. I switched the RTA to another mod and it was the same as the second mod. I did it a third time. All same settings. All the mods were VV/VW.

Anyone ever do this?

Every mod utilizes a diffrent chip, so they may differ abit. Same goes for say ohm readings. One mod says 1.1, the other 1.2 and the third may say 1.0.
I don't know exactly why this happens nor which one that is reading the correct ohm.

That's why i build using my ohm meter and then test with my multimeter aswell just to check how correct the readings are. (Only when i build low ohms though)
I trust my multimeter more than the reader. Granted i'm more of a mech user so that's why i trust my MM more.

I'm not to well versed with the regulated chips so i can't give a better answer than this. :/ I'm sure someone else can.
This is also why pbusardo does his tests to check how correctly the mod fires. (If you've seen any of his reviews you'll know what i mean with tests)

Well, the ohms are all close in the hundredths. The mods are upper-end with known chips. I just noticed that the odd brand, I only have one, was the first one. The other three mods have the other brand. It was just a notice on my part about the chips. I don't know that it really means a whole lot.

Just thought to mention my experience.

The chip processors in various regulated mods vary by the way they send current to the atomizer in a process called PWM, or pulse width modulation.

Many of the cheaper chip sets have what's termed as the "rattlesnake effect", putting out 33.3 Hz. These can taste quite warm or harsh to sensitive vapers. The low Hz frequency may have an audible low frequency rattling sound that some people can hear, and can be demonstrated on an oscelloscope as jagged lines.

Vamo

The more expensive chip sets use a much higher Hz rating. For instance the Provari, MPV, and DNA chips output around 800 Hz and usually provide what is described as a smoother vape. This frequency shows up as a flat line on an oscelloscope.

Why Mods that Use the Cheap 33.3 Hz Chip don't Vape the Same as a Provari, DNA-20, etc​

Yes, for cost considerations and wanting to be of service to a new vapor, I always suggest the value of the MVP. And since I am not a tube mod person, and so long as they don't offer a box mod, I tend to stay away.

I was checking with the YiHi and DNA mods that I have. There are a lot of variables and my test was not scientific in any way. I did also use a digi-meter to just get a measure of the RTA's reading.

Whatever I use, I still believe the MVP, and SVD, are the best deal for a new person that has little knowledge/experience. Most are going to get shinyitis and get something else in two months anyway.

Thanks for chiming in...both.
