I just ordered this pv and just got it yesterday. This is my first experience with VV and I gotta say I like it a lot. I was wondering if anyone else has this same unit. The website that I bought it from says to push the activation button 5 times to display the resistance and the remaining battery, but when I do this all I get on the display is 0.0. I am using a 510 to 510 sealed drip shield adapter with a 3.0 ohm carto, would this prevent the unit from displaying the resistance and the battery charge remaining? Without the adapter I still get the same reading of 0.0. I am using 18350 batteries from my silver SD, so I don't know if that might also be the problem. I have some AW IMRs in the mail that should be here today. Anyone else have this happen or possibly know what I am doing wrong?
