ABSTRACT:
Uniform and repeatable formation of a resistance element on a substrate is achieved by spinning the coated objects which are still in a wet state while rotating them about an orthogonal axis to subject the wet indicator formulation to centrifugal forces which forces the indicator formulation into contact with the substrate.
