A Newa Pproacht O Digital Thermocouplined Icators
Author(s): Rick Lagrand
Abstract/Introduction:
In the past 10 years Digital Temperature Indicators have come into common usage in industry. Technological advances have made possible large bright displays that are visible from significant distances,without parallax. Stable and reliable digitizing circuits have been designed. Digital linearization techniques have been implemented and thermocouple reference junction networks which are relatively free of ambient temperature variations have been devised.

Calibration Of Temperature Systems
Author(s): Richard H. Reed
Abstract/Introduction:
In the last decade, industrial fields have experienced rapidchanges in their measurement and control technology resulting in equipment of a more complex and expensive nature for our maintenance departments to service. To give you an idea of these changes, industrial fields have developed from simple manual control to hands-on analog control to present-day complex computer control.

The Electronic Thermometer For Human Use
Author(s): H. P. Voznick, K. Junkert
Abstract/Introduction:
Everyone knows that the body does possess a temperature and that this can be measured by inserting a mercury thermometer in the mouth. In the past few years, electronic thermometers, particularly those that have digital readout are being used more prominently in hospitals for measuring patient temperatures.

The Application Of Automated Testing To Guaranteed Product QUAL!TY
Author(s): Loebe Julie, Julie Resea
Abstract/Introduction:
Conventiona ch Laboratories product quality control makes use of many test shortcuts in . . I.. order to keep restrng costs down. tach shortcut (omitted or abbreviated test) increases the possibility of passing a defective product to the final consumer or user. This paper discusses the methods that can be used to increase the thoroughness of testing 10 to 50 times by properly applying modern automated hardware and software systems.

Automated Calibration System Data Analysis
Author(s): Richard Calhoun
Abstract/Introduction:
The Navy Metrology Engineering Center provided nineteen Automated Calibration Systems (Model ACS-200) to seventeen Navy Calibration Laboratories and to two Marine Corps Supply Centers. Instruments calibrated using the ACS-200 are oscilloscopes, oscilloscope plug-ins, and meters. Variables data for these instruments are recorded automatically on magnetic tape cassettes. This feature is part of the ACS-200 operating system software. The scheme to collect, store, and utilize these data is currently under way.

A Comercial View Of Reliability Predictions And Product Testing
Author(s): Allan S. Golant
Abstract/Introduction:
The following brief viewgraphs cover the general outline of a paper whose main purpose is to cover an approach which has been and is being used successfully by a major computer manufacturer. The actual paper delivery will go into more detail and will note those areas which are variable for each individual firm. Nevertheless, the essence of a Reliability Engineering Program -- Analysis and Product Testing, will focus on the need for the efforts, the value derived and the relationship of such efforts to related QA, Engineering and Marketing functions.

An Automaticr MS/DCT Ransferin Strumen
Author(s): Louis G. Cox, Norbert L. Kusters
Abstract/Introduction:
The design of an instrument to perform automatic substitution and comparison between the rms value of an ac voltage and a stable dc voltage is described. An rms/dc converter circuit incorporating a multijunction thermal converter is the transfer element. An FET-switched input amplifier connects the ac and dc sources alternately to the converter circuit. The output voltage of the rms/dc converter with ac and with dc inputs are sampled and stored, and the amplified difference displayed on a panel meter or chart recorder. Accuracy is 2 20 parts per million (ppm) of input range of 10 to 200 volts at frequencies of 50 Hz to 1 kHz.

Safety Measurements In Hospitals
Author(s): Patrick L. Tarzian
Abstract/Introduction:
In order to maintain correct operation of electronic instrumentation, periodic maintenance must be performed and documented. The frequency of periodic maintenance is done according to the type and usage of the instruments. This is standard in the industry where exact measurements are mandatory. This concept of maintaining correct instrumentation is also being applied to biomedical instrumentation and systems. Calibration plays a major role in correct instrumentation.

Quality Control In A Calibration Laboratory
Author(s): Rolf B. F. Schumacher
Abstract/Introduction:
Addressing itself to the measurement of quality of the output of a calibration laboratory as a concrete example, this paper may serve as a blueprint for comprehensive quality measurements of the output of any service organization. It shows how the degree of compliance to technical, legal, and contractual requirements can be measured in a calibration laboratory. Emphasis is on measuring the in-tolerance conditions of measuring instruments, the quality of labeling and identification, traceability, records, data, establishing recall dates. Resulting quality data identify trouble areas, operator weaknesses, etc. and indicate where corrective action may be required.

Digital Indicators For Precision Linear Keasurkmrkt
Author(s): William L. Kitchens
Abstract/Introduction:
The maufacture of many products, both mechanical and electronic, has required continuous development in order to achieve better reliability and to achieve miniaturization of components and assemblies. !PheW3 factors create a need for parts which are fabricated to precise limits of dimensional tolerance. In recent years we have seen the advance of measurement requirements from the order of .0005 inch to where today tolerances of .OOOl inch, as well as 50, 20, or 10 microinches and even less are becoming commonplace.
