Manual Overview

The HP-69500A series operation manual provides detailed instructions for operating and servicing programmable resistance cards, specifically models 69500A through 69506A and 69510A through 69513A. These cards are designed for use in multiprogrammer units to produce variable resistance outputs proportional to programmed digital data, which can control programmable power supplies or other devices. The manual emphasizes troubleshooting, error codes, diagnostics, calibration, and adjustments. Each model features identical address decoding, data storage, and relay switching circuits, but varies in the precision resistors installed. The 69500A model is unique as it allows customization by the user, lacking pre-installed resistors. The manual provides board-level guidance for installing and programming these cards, detailing how a 16-bit word from a remote computer or control panel programs the cards. Twelve bits represent data, while four bits address the card slot. The manual also includes safety precautions, emphasizing proper grounding and avoiding live circuits during maintenance.
