Re: Help!!!
SA of my part is 23.538, according to the 720 rule to get .7 mills, I need 6 amp CD, current set at .98 for 84 mins, with a peak voltage of 15 v
This brings me to a couple of questions:
1.can you explain how to "set" the current, I read about this but I'm not quite sure if I am understanding.
2. The 720 rule says peak voltage is 15 v, I have a 12 v charger, as usual I'm a little short( I'm 5'7" tall) is this a problem?
These numbers are on, are you using the 720 calculator? A couple of points for you on these calculations. The CD can be changed from 3 to 6 ASF to allow for different short comings in a system. Don't go below 3 ASF because the coating grown will be too soft and pore size too large to give good results. If you only have 12V capability, drop to a 4.5 CD for a projected peak voltage of 11.25V. It will drop you amp setting to .74A and raise the run time to 112 minutes for the same thickness coating. The peak voltage is only a calculation. It is usually close but due to all the parameters that will effect it (tank temp, connections), it will not always be right on.
Using the light bulbs, you have to measure the resistance of the bulbs and using Ohm's law calculate the amperage they will allow at the voltage they run at. Run the needed amount of bulbs in parallel to add up to the amperage you want. You can see a light board I made for mine in my picture album on the 3 gal setup.
Using the dimmer setup, you adjust the dimmer to vary the voltage to achieve the amperage you want.
With these methods accuracy is difficult and tweaking of the voltage is needed during the run.

, I may be able to come up w/ pix later on.
