i tested one with ECD last night..
i give up on VV mode entirely, same as vmax basically ..
only tested it with a 1.8Ω.
single battery mode it tops out at about 13W full charge .. changes on whether battery
is charged or not.
3 to 15W single battery (full AW imr 18650)
6 (3W setting)
6.9 (4W...
the other 2 pictures in that folder are one with the 18650, i make it about 5.5W from memory (same 3W setting) and with dual batterys but before being topped up to full charge.
That test photographed is about as bad as it gets for this device, lowish ohms, minimum watts and dual fully charged...
Sorry, but this is just plain wrong.
The RMS voltage obtained correctly, then used in a simple formula like P=V*I .. will give you the EXACT power, regardless of waveform. If its a continuously repeating one of course, something like audio .. it changes all the time.
Any repeating waveform you...
Well I got a zmax to have a play with yesterday, been busy today, it looks to me that it does not ever go below 32.7% duty cycle.
With dual batterys .. fully charged, zmax set to 3W, 2ohm carto .. calculated power is over 9W.
Not tried it yet, but if the peak voltage holds up on 1.5ohm .. it...
short the 2 pins closest to the output connector, power the meter up for more than a few seconds to reverse the display Tom, a butter knife does a good job..
Ok, watched all the video now :) .. great little demo.
So if you want to be real technical .. this also means that if the resistance on the meter says 2.86ohm .. then plug 2.96ohms into your chart to take into account the 0.1 the meter has removed from the reading, this should give you a more...
its spot on .. on topic.
you are just entering into the reasons why the reviewers have not been comfortable using rms.
I have larger CRO's .. about 5 of them, but a nano has been on my shopping list for ages. always out of stock when I look :)
raider: do you really think that mods should be...
the meter works on both pwm and non pwm mods.
linear mods like provari..
Voltage
Current
Power
Resistance
PWM mods (ego, vmax)
Peak Voltage
RMS Voltage
Peak Current
Average Power
Resistance
Duty Cycle
Frequency
fair enough, I'll stand corrected on that .. didn't think about that one enough. you lose all the peak voltage by the time it gets to the load.
that being said .. you are using an inductor about half the size of a house brick and we are talking about ecigs. even the cap is pretty chunky, half a...
coffin nails, i can use an ego C on an ego twist, no problem at all, the twist goes down to 3.2v.
what many think this thread is about is the numbers are wrong, yes .. but it does not matter. the real problem is that a Vmax minimum setting is really 4.5v .. you cannot use a wide range of devices...
i will answer the question i asked previously about a 300v battery ..
at 1% duty cycle the Vaverage will be 3v, if you use the average into a 2Ω atty, the power calculation (v^2)/r gives 4.5W
now .. in reality .. you are applying 300v to a 2Ω atty for 1% of the time.
when it is on .. the atty...
the provari is perfectly accurate.
it puts out DC which is exactly the same as rms, on DC .. the average is also the rms, so it also measures correctly on a normal meter.
this issue ONLY applys to pulsed output mods.
watching this thread ,, will be interesting..
I think VG changes after a while, in the bad old days pre ego, VG juice used to leave a yellow greasy residue in the fill if not cleaned every day or so.
