0.0ohms shows if they tightened to hard and broke the O-ring (shorted reads 0.0ohms) it is a common problem with vamo's
You can Google (vamo 0.0ohms) or (vamo ohm error fix) and they have all sort of fixes.
I read up on it before I purchased mine (I own a Vamo 3). Certainly didn't want one if I wouldn't be able to fix it myself.
You are correct though 9.9ohms with nothing on it or if nothing connected but if shorted
it will show 0.0ohms
with or without atty on it.
I'm thinking they probably got it to work as they have not come back to check answers in awhile.
Figured out how to turn it on. I'm guessing they were new to vamo as they stated only what it reads when batteries first installed. No mention if they clicked it 5 times or not to start it.
They might have thought just stick batteries and it works witch it wont (5 clicks is a must to turn on)
Also 3.7 volts is what battery rated voltage and what vamo first reads. You can not check the correct volts until it is actually on.
All FT 18650 and 18350 batteries say 3.7v . They charge to 4.2 of course Panasonic 3.7volt
