Using iTaste VV as Ohmmeter?

[chabos]

Hey everyone, I intend to get into coil rebuilding in the near future, so I asked a guy at my local shop for some advice. Since I'm getting an iTaste VV, I wanted to know if I could use this as a meter or if I needed a dedicated meter. He told me that while the meter on the VV would work and is protected from firing a shorted coil, it wouldn't get a very high accuracy and that it was better to use an external meter. Can anyone tell me if this is correct? I'm sure that more accuracy can't hurt, but I'd imagine that if the built in meter is accurate enough for the VW function it's probably good enough for rebuilding coils, right?

I use the iTaste SVD and VV/VW 3.0 to check resistance all the time. I've never had an issue with accuracy on either of them. Both read the same 1.3 ohm coil, both fired it and both vaped like a champ so it's definitely useful for that very task.

The only thing you need to be aware of is the limitations of the VV/VW 3.0, anything below 1.3 isn't going to fire. So you need to make sure you hit 1.3+ ohms otherwise it's just going to read the resistance and fail to fire.

I've had 6 iTaste 3.0s... all given away but the 2 for wife and daughter.

Using a Fluke 88 as reference... three were accurate down to 0.5Ω +/- 0.1Ω. One had a +/- range of 0.3Ω (0.6Ω total), and two consistently and repeatedly read 0.2Ω higher (again, tested down to 0.5Ω) than reference.

I would trust them for above 1.3Ω, which, as has been stated, is the lowest you should go with a 3.0... but not for sub-ohm measurements. If you intend to run a mech & sub-ohm atty at some point, buy a DMM - you will need it for voltage and continuity testing anyway.

Maybe not all of them do, but my wife's VV v3 fires below 0.9 ohm. I used it to pulse out a new build on the KFL+ this weekend while out of town. I had no other meter and was glad to have it. That it fired and let me poke the coil into final shape was a nice bonus.
