DC Fundamentals Unit 1 – Trainer Familiarization
Exercise 3 – DC Board Familiarization ......................................................................................
EXERCISE OBJECTIVE
When you have completed this exercise, you will be able to use specific trainer functions on the
DC FUNDAMENTALS circuit board. You will verify your results with voltage and current
measurements.
DISCUSSION
- The DC FUNDAMENTALS circuit board is divided into 10 training areas called circuit
blocks. - Each circuit block consists of circuits designed to introduce the student to electronic
principles - Each circuit block has a drawing or schematic that shows how every component in the circuit
block is electrically connected. - Test points are located at each end of the circuit blocks and accept test leads directly.
Terminal posts and alligator clips are provided for those test leads that do not readily
connect. - Dashed lines between two test points show that no electrical connection exists. A two-post
connector can be used to complete the connection. - Each circuit block has a title to identify the circuit type and function.
- Most current measurements in this volume will be in the milliampere range.
