Abstract

See full text

A coating dispensing device includes a trigger assembly for actuating the coating dispensing device to dispense coating material and a nozzle through which the coating material is dispensed. The coating dispensing device further includes a source of voltage and a voltage multiplier for multiplying the voltage. The voltage multiplier is coupled to the source. An output terminal of the voltage multiplier is charged to a high-magnitude electrostatic potential and is adapted to charge coating material as the coating material is dispensed from the dispensing device. The coating dispensing device further includes a circuit for providing a visual indication of the voltage at the output terminal. The circuit for providing a visual indication of the voltage at the output terminal comprises a first impedance across which a portion of the voltage at the output terminal appears and an amplifier. The output terminal of the amplifier is coupled to a light source for providing the visual indication of the voltage at the output terminal of the voltage multiplier.
