Abstract: An electrostatic sprayer includes a spray gun having a nozzle at which pressurized spray media and pressurized air are combined into an atomized mixture. A generator electrostatically charges the atomized mixture at the nozzle. The generator may also electrostatically charge the pressurized spray media, or the pressurized air, or both at the nozzle. An input device of the spray gun is actuable by a user to vary a flow of the pressurized spray media to the nozzle. A main unit is connected to the spray gun with a hose via which the pressurized spray media and the pressurized air are communicated to the spray gun. The main unit has a first power mode in which a battery powers component(s) of the electrostatic sprayer. The main unit also has a second power mode in which a power source spaced apart from the main unit powers the component(s) of the electrostatic sprayer.

Abstract: A method of testing an electrical conductor assembly having a plurality of networks is divided into a first test routine and in further test routines. A conductor assembly is tested in each test routine. In a first test routine, a field test for detecting short-circuits between the individual networks and a resistance test for detecting open-circuits in said networks are implemented. From the data sets resulting from the field test, complex conductances are determined between at least one antenna employed in the field test and the tested networks, which are used as reference conductances for the further test routines. In the further test routines short-circuits between the networks and/or open-circuits in the networks are detected by sensing a complex actual conductance between each network and at least one antenna and by comparing the actual conductance to the reference conductance. In addition the invention relates to an apparatus for implementing the method.
