voltage - I need help buiding a HV capacitor circuit

I want to build a circuit to use thisHV power supply to charge up 4 of theseHV capacitors. I do not know how to size the resistors needed. I also want a way to check the voltage with a multimeter to keep from over charging the caps. I plan to make a trigatron to fire the caps. The caps are in series with bleeder resistors and need to be charged to 4.5Kv.
