How To: Test Device Under Load -- Prodigy/Other Devices

[CaSHMeRe]

Posted this in the Resistor Thread ... Thought it could help others out wondering what type of voltage they are truly getting at the atomizer

Here's the Breakdown:
Prodigy V1: (Batteries - (2) Tenergy RCR123 - 750mAh - Fully Charged -- Without Resistor --Resistorless Switch Needed)
At Atomizer -- 6.62v
Under Load (True Voltage) -- 5.65v

Prodigy V1: (Batteries - (2) Tenergy RCR123 - 750mAh - About 95% fully charged -- With Resistor -- Standard Prodigy from PureSmoker)
At Atomizer -- 6.53v
Under Load (True Voltage) -- 4.84v

Prodigy V2: (Batteries - (2) Tenergy RCR123 - 750mAh - About 95% fully charged -- With Resistor -- Standard Prodigy from PureSmoker)
At Atomizer -- 6.55v
Under Load (True Voltage) -- 5.15v


PS USBpass PT (20g Wire -- 6ft) <-- Standard USBpass From PureSmoker
At Atomizer -- 5.07v
Under Load (True Voltage) -- 4.28v

PS USBpass PT (24g Wire -- 3ft long) [One of original Prototypes -- Only a couple sold to those who wanted]
At Atomizer -- 5.07v
Under Load (True Voltage) -- 4.03v

Protege: (Battery - (1) Tenergy 14500 - 900mAh - About 95% fully charged)
At Atomizer -- 3.97v
Under Load (True Voltage) -- 3.77v

How to test load

First -- Tools Needed
1) Prodigy (or any device for that matter)
2) Female Atomizer connector
3) Male Battery Connect
4) Wire
5) Multimeter
6) Perhaps an extra set of hands
7) Solder/Electrical tape

Batteries tested are the ones Casey uses day in and day out ... They are probably at about 70-75% fully charged.

Picture of equipment:


Picture of voltage tested at adapter (Non Complete Circuit/Not Under Load) -- 6.53V


Picture of completed Circuit (901 atomizer on the end). Testing Leads to check loaded voltage. -- 4.84v


Closeup, of exposed wires allowing you to put multimeter probes there to test.


Hope this helps people understand loads and test if they want to

Really should sticky this and thanks!

Bump.

I agree.

[ChefChris]

I concur, sticky this.
None of this seems to be common knowledge yet, I've seen wayyyy too many people asking about the voltage of your devices. This is a great reference :-)

I'm sure Steve doesn't want us to try and duplicate this on our own. He has done a lot of work on this and it is valuable info.

Maybe it's to early for me but i just don't get what you mean.

[googled]

Crazyily simple and so obvious. I wonder how many people tried testing at the atty coil lol. I'd wondered how you would load test. Thanks Steve this will be incredibly useful.

Check out the Protege sitting there... Aint it cute... ???

Two questions Steve, Are you using an LED in the end of the atomizer you have wired up to create the load? And would an actual atomizer boiling juice pull a bit harder than an LED?

Hey Vapnaway ... No, that is not an LED on the end. Just a 901 I listen for the sizzle of Depends on the resistance of the LED. Many LED's carry around the same resistance of an atomizer (depending on color of LED)

thanks man!
