What does a Matrix Bath Attendant do?
Maintains electrolytic baths in operating condition for plating phonograph record matrices: Draws sample of solution from tanks, using pipette. Tests strength of solution, using hydrometer, and adds specified amounts of metallic salts, acid, or water to solution as needed. Examines anodes for specified size and for position in baths. Activates controls and reads meters to test electrical connections for open or short condition.
