This document contains 20 competency-based examinations with student and instructor manuals for electronics and instrumentation occupations. For each of the examinations, the student manual contains the following: the competency, the performance objective, directions, the materials and equipment needed, a space to note time started and time…

Discusses developments in electrochemical instrumentation, including the role of computers, measurement/control instruments, present needs and future prospects. Indicates that microprocessors are used primarily for data processing, and that progress depends on noninstrumental factors such as electrode materials. (Author/JN)

Describes an interface that uses semiconductor metal oxides to detect low gas concentrations. Notes the detector has long life, high stability, good reproducibility, low cost, and is able to convert the gas concentration to an electrical signal with a simple circuit. Theory, schematic, and applications are provided. (MVL)

Discusses the use of microcomputers as a universal instrument to replace more expensive instrumentation in many traditional labs. Describes the availability of microcomputers as inexpensive educational tools which can be used successfully in labs with minimal requirements on the computer. (SK)

Running experiments and grabbing experimental data are great ways to learn and teach science and mathematics. Data grabbers are instruments that capture physical data in electronic form for graphing and analysis in graphing calculators and computers. Describes some data grabbers and points to items in their gigantic support system. (PVD)
