Sorry for the lack of information. Here is the text from the first post in the Calivapers thread.
"So, I had nothing better to do but setup a rig to test some mech mods based on the conversations here.
An Astron power supply as the main power source and connected it to a 1 ohm 100W resistor for one test and 2 1 ohm resistors in parallel for a .5 ohm test. Voltage reading was taken at the mod.
One problem I ran into was the regulator would not output over 6 amps at 3.7 volts into a .5 ohm load. It needed to be at a higher voltage, so I used 7 volts to output 13 amps of current through the mod. This is will come out to a load of about .3 ohms at 3.7 volts.
The testing is to isolate the mod itself and to get actual voltage drop and current flow and not be influenced by atomizer and battery resistance.
Note that firing the device with varied pressure, pushing the button to the side when firing, etc., causes voltage variations. The mod is fired multiple times and the most consistent voltage is recorded."
My take away is that everything tested gets tested with the same setup, while removing the variables. Gives a standard for comparison.
