ABSTRACT:
An electrostatic spray gun having a self-contained power supply including a high voltage electrostatic voltage and current source, with circuits for monitoring the voltage and current and developing a frequency signal based on the monitored voltage and current, circuits for modulating the frequency signal with a radio frequency carrier and transmitting the modulated-carrier signal to a remote radio receiver, where the signals are demodulated and converted to a digital display representation of the monitored voltage and/or current.
