Model 595 Quasistatic CV Meter
Quick Reference Guide
A GREATER MEASURE OF CONFIDENCE
INTRODUCTION
This reference and programmingguide contains condensed
specifications, descriptions of the various features and in-
formation for using the Model 595. Also, IEEE-488program-
ming information and several example programs written for
commonly used controllers are also included to get the
Model 595 "up and running" on the bus.
The Model 595 QuasistaticCV Meter measures capacitance
using a unique feedback charge method. This method cor-
rects capacitance readings for background leakage current.
A built-in IEEE-488 interface, plotter driver and labeled grid
program enable the Model 595 to plot IV or quasistatic CV
curves for a variety of semiconductor materials and
components.
