13.12.1  Soldering and Wiring

A.  Objective          

To review the fundamentals of good soldering techniques and good wiring practices.

B.  Assignment

The trainer will introduce the various types of soldering equipment and will review the basic principles of good solder joint production and good wiring practices.

The trainer will present methods and precautions for soldering and working with semiconductor devices.

The trainee will be expected to perform practical exercises assigned by the trainer to gain experience in hardwiring components and circuits.

13.12.2 Analog and Digital Meters

A.  Objective

To introduce the trainee to types of meters, their operating principles, what the meters actually measure, their use, and precautions regarding their use.

B.  Assignment

The trainer will review the fundamentals of meters and their use. Included in the review will be the following:

  1. Direct current meters
    1. d'Arsonval movement
    2. ammeter
    3. voltmeter
  2. Alternating current meters
    1. voltmeter
    2. ammeter
    3. wattmeter
  3. Ohmmeters
  4. Multimeters
  5. Peak reading voltmeter

The trainee will perform exercises with meters to gain practical experience in their use, the proper choice of meter for a given application, and interpretation of the manufacturer's specifications for individual meters.

13.12.3  Oscilloscopes 

A.  Objective

To acquaint the trainee with various oscilloscopes and accessories.

B.  Assignment

The trainer will introduce oscilloscope equipment and will discuss equipment capabilities for given measurement applications. Among components to be discussed are:

  • portable oscilloscopes—line and battery powered
  • digital storage oscilloscopes
  • vertical amplifiers
  • time bases—normal and delaying
  • differential comparators
  • probes, their selection and use

The trainee will be expected to gain familiarity with oscilloscope equipment and its use through practical experiments assigned by the trainer. The trainee is also encouraged to experiment with the equipment independently—to learn how to select the proper equipment for a given measurement and to become aware of equipment strengths and limitations.

13.12.4 AC and DC Power Supplies

A.  Objective

To introduce the trainee to AC and DC power supplies.

B.  Assignment

The trainer will present the AC and DC power supplies, including transformers, batteries, generators, and solar cells, and will instruct the trainee in their applications and use.

The trainee will be expected to become familiar with these devices through practical exercises assigned by the trainer.

13.12.5 Pulse and Function Generators

A.  Objective

To introduce the trainee to pulse and function generating equipment.

B.  Assignment

The trainer will present the pulse and function generating equipment and will instruct the trainee in its use.

The trainee will be expected to become familiar with the equipment through practical exercises assigned by the trainer.

13.12.6 Calibrators and Standards for Electronic Instrumentation

A.  Objective

To introduce the trainee to laboratory standard instruments, standard calibrators, and local operating procedures regarding their use.

B.  Assignment

The trainer will present the calibration standards and standard electronic instrumentation.  Types of standard instruments to be introduced will include:

  • voltage standards
  • current standards
  • frequency standards
  • time standards
  • resistance/impedance standards

In addition, local policy, procedures, and constraints regarding their use will be covered.

13.12.7 Special Purpose Instrumentation

A.  Objective

To introduce the trainee to instrumentation for making special purpose measurements and for acquiring/accumulating specialized data.

B.  Assignment

The trainer will introduce the special purpose instrumentation and describe its use.

The trainee will be expected to gain practical experience with the equipment through exercises assigned by the trainer.

13.12.8 Automated Data Collection Systems

A. Objectives

To provide the trainee with an introduction to the types of automated data collection systems and their use.

B. Assignment

The trainer will introduce automated data collection systems and their interface with data gathering sensor systems. Basic programmable calculator programming and "canned" programs will be presented.
