580/680 Scientific Computing System — Maintenance Series: 26.268 Digital Voltmeter

Maintenance manual for the EAI Model 26.268 Digital Voltmeter (DVM), a plug-in analog-to-digital conversion unit designed for the EAI 580/680 Scientific Computing System. The DVM provides a five-digit BCD successive-approximation readout over a ±10 V range (20% overrange to ±11.999 V) at 50 or 60 samples per second, with 500 MΩ minimum input impedance and ±0.01% full-scale accuracy. The manual covers physical description, installation, theory of operation (unloading amplifiers, comparator, gated resistor matrix, BCD counters, timing, and power supply), trouble analysis, calibration procedures, replaceable parts, and schematic drawings.
