b. Demonstrate to the TA that you can:

i. Turn on PC

ii. Locate webpages shown page

iii. Turn off PC

2. Meter and Power Supply

a. Exercise - Measuring DC Voltage

i. Batteries

b. Demonstrate to the TA that you can:

i. Turn on the meter

ii. Select the proper setting

iii. Measure the battery voltage - all voltages should be positive

iv. Answer the following questions:

(1) Which side should the red and black test probes be on to get positive voltage measurements?

(2) What voltage reading do you get when the red and black probes are connected together?

(3) When the red and black probes are both touching the plus side of the battery terminal what is the voltage reading?

c. Exercise - Power supply usage

i. Adjusting the output voltage

d. Demonstrate to the TA that you can:

i. Turn on the power supply

ii. Select the proper setting

iii. Adjust the voltage to 5.0 volts

iv. Measure the voltage of the power supply using the meter

e. Exercise - Measuring resistance

i. Resistance box

ii. Common items

iii. Self

f. Demonstrate to the TA that you can:

i. Turn on the meter.

ii. Select the proper setting.

iii. Obtain resistance measurements that reflect the changes made to the switches of the resistance box.

iv. Obtain resistance measurements that reflect the changes made to the switches of the resistance box.

v. Measure the resistance of some common items.

vi. Measure the resistance of yourself from one hand to the other.

3. Oscilloscope and Function Generator

a. Exercise - Hearing the function generator signal

i. Hear the different sound frequencies generated by the function generator by adjusting the frequency

ii. Hear the different qualities of sound generated by the function generator by changing to different wave forms (square, sine and saw tooth)

b. Exercise - Seeing the function generator signal

i. Connect the function generator output to the oscilloscope input

ii. See the change in frequencies generated by the function generator by adjusting the frequency.

iii. See the different wave forms (square, sine and saw tooth)

c. Demonstrate to the TA that you can:

i. Turn on the function generator and ocsilloscope

ii. Select the proper setting

iii. Adjust the function generator to sine wave at 500 Hz and view about two or three complete cycles.

iv. Adjust the function generator to a square wave at 1000 Hz and view about two or three complete cycles.

v. Adjust the function generator to a saw tooth wave at 5000 Hz and view about two or three complete cycles
