1 Introduction to Engineering Camera Lab #4 – 2 Task #1 Agenda Overview of Camera Lab #4 Learn about operation of oscilloscope Review Task #1 Procedure Conduct Task #1

2 Camera Systems: Reverse Engineering Shutter:  Mechanical Flash:  Electrical Case:  Manufacturing & Materials

3 Overview of Camera Lab #4 Measure of voltage at different points in the circuit over time using an oscilloscope and voltmeter Watch the voltage change on the oscilloscope Record and analyze the data

4 Overview of Camera Lab #4 Task 1: Watch charge on the capacitor increase and note when the neon indicator light comes on Task 2: Watch the change in the voltage when the capacitor is discharged Task 3 (Optional): Use a voltage divider to measure flash trigger transient.

5 What’s an Oscilloscope? Instrument used to measure voltage Has two channels so you can measure voltage at two points in the circuit at the same time Has a display screen that shows a graph of voltage versus time

6 Oscilloscope cont… You can control the time scale on the horizontal axis of the display screen.  For example, one division might represent a second or a millisecond or some other time interval You can also control the vertical scale The oscilloscope will store the data You can use a pair of cursors to identify two points of interest on the graph and the oscilloscope will calculate and display the difference between those points.

7 Task #1 Procedure Summary Do “preliminary tasks: in Section 1.2 of the Camera Lab #4 procedure Follow the detailed steps under Task #1  Test box power switch OFF  Connect scope and DMM  Turn test box power switch ON  Gather data

8 Assignment Be sure all team members have the data from Task #1 before the class ends Make/check calculations for Task #1 Answer questions under Task #1 in “Report Instructions” Read Task 2 procedure
