Page 13: Introduction
A single CPU board now performs the functions previously performed by the 410 analog and control boards. The transformer has been eliminated and replaced with the same switching power supply used in the 2487. Waters part number WAS081226 can be used to order power supplies for use in either the 2487 or 2410 detectors. -
Page 14: Serviceability Improvements
A 2487 style analog noise and drift test is built into diagnostics. Each valve is a self-contained unit. Valves snap in and out for replacement without the use of tools. The 2410 design incorporates quick disconnects instead of screws. This change makes service of the detector simpler and faster. -
