Modification Of The Beckman Spectrophotometer With An External 'C' Battery Supply And A Voltage-Checking Arrangement.

Abstract

Several objections are noted to inverting the Beckman Spectrophotometer whenever "C" batteries and/or plate or screen voltages of the amplifier tubes need changing. These objections become more serious in cases where the optical alignment of accessories cannot be disturbed by movement of the instrument. A modification is described for placing the "C" battery supply external to the spectrophotometer and incorporating a voltage-checking arrangement. Circuit diagrams for pre-and post-conversion are presented for the components, all of which are normally available from an electronics stockroom.
