Hi Becky
Monitoring voltage alone with no reference to other parameter
settings would probably be a waste of time. Assuming you are
monitoring a spray system where all settable parameters are kept
constant (you spray same coating all the time)then
monitoring voltage over time for any individual nozzle/electrode
hardware set-up would be useful. It is important that you are able
to relate voltage with the other parameter settings particularly
plasma gas flows, current, etc. and hardware.
An interesting point is that a few set voltage to a specific point
and keep this constant, so that they always maintain a constant
power output. In this case plasma gas make-up and flow become the
variable.
Hope this helps.
Regards Gordon
