Voltage output/readout with meter

[emonty]

Question,

when you attach a voltage meter to the Provari, what should be the voltage readout on the meter when pressing the button (not the readout from the LED of the Provari) if you set it for instance to 4.0V?

 

[rolandpibb]

According to the videos I've seen. If you set it for 4.0 volts, it's 4.0 volts cold AND 4.0 volts under load.

 

[emonty]

mmm, then something is wrong as I only get 6V or whatever the charge of the battery is....

 

[Frick]

What voltage meter are you using? Do you notice the voltage changing if you change it on the PV as you vape? If it's stuck at 6V, you'd definitely know it just from vaping it.

 

[emonty]

screw on voltage meter from COV but also checked with my multimeter. Voltage is not changing whatever I set it to, it just gives me straight 6V or whatever the voltage of the battery is at. The LED on the Provari gives different readouts but in effect it does not change anything. Ohm rating works also fine, no error messages, tried different atomizers/cartomizers...looks like it is broken.

it just gives me straight 6V or whatever the voltage of the battery is at

So it does change, but only between battery voltage and 6V? Or it doesn't change and always shows 6V?

 

[emonty]

It changes as the battery drains, yes otherwise I would have the first mod that can last forever

OK, I'm not making any sense from your post.

The battery, fully charged, will only read 4.2 volts, not 6 volts. The boost circuitry in the ProVari will output 6 volts, no matter what the voltage of the battery is. So the reading changes? Or it doesn't?

 

[emonty]

Let me try to explain better: When I put a fresh battery in the provari, set the voltage to let's say 4.2V, the output reads on the voltage meter or the multimeter 6.xV. If I take a battery that still has 5V left, the multimeter or voltage meter reads 5V.
On both occasions the LED on the Provari reads whatever I had set it to.
Practically: all atomizers I put on the provari give me the voltage on what the battery is, not what I have set the Provari at.
Makes any sense?

If I set the Provari to 3.3V, take an HV 3.5 Ohm atomizer, it kicks like I am vaping on 6V, not on 3.3V

No, it is still not making sense. The maximum battery voltage is 4.2 volts so as soon as I read, "battery that still has 5V left", either means you are using battery I have ever never heard of and should not be using, or there a complete breakdown in communication.

ok I will try Mickey Mouse language:

1.) Insert one 3.7V battery in Provari
2.) Screw in a 2.5 ohm atomizer
3.) Set voltage to 4.5V
4.) Vape, but it gives a much stronger vape then what one would expect, so let's check this...
5.) Unscrew atomizer
6.) Screw in a voltmeter on the Provari
7.) Screw in an atomizer on the voltmeter
8.) Press button and read on voltmeter 6V, not 4.5V what the Provari is set to

I simple terms: whatever I set the provari to, it gives 6V or whatever volt the unit can still boost from the battery power

 

[Hoosier]

Ah, now that makes sense. All your measurements were from the PV and not the battery.

Yes, you have a defective ProVari. Contacting them and getting an RMA is the only thing left to do.

Sad to see a PCB die, but it happens.

 

[emonty]

ok, that is what I thought, pfff language barrier, no, really who is saying that

 

[Hoosier]

Eh, I've had teenage sons, I've navigated worse confusion on what is said versus what was meant.

 

[emonty]

lol, Yeah I hear you bro, got one too, thxs for your confirmation that it is broken. Will send it back for the upgrade, that way I have hit two flies with one shot

 

[Krprice84]

yea i was confused too... cuz you did say that if you put a battery in that has 5 volts still on it then you will get 5 volts out... but that doesn't exist, there is no single cell lithium battery in an 18490 or 18650 format that will EVER put out 5 volts (it will vent flame or at least burst or leak or fail if it ever got near that high)... so it was pretty confusing

either way, are you getting that voltage with a load attached, because i do know that i've read that provape suggests not to use the provari without a load (carto/atty) attached, and from the literature, i am thinking that it will not put out the correct voltage by design if there is no load because it is made to sense the load and if it is open it will not put out correctly, though i think it is supposed to not put out anything, so something is still wrong

but for the future, i would look into wether or not you can actually check the output voltage of the provari with just a multimeter touching the output contacts, because you inherently can't have a load on the device if you are touching a multimeter to the contacts...
