2. Lay out the circuit on a piece of paper so you can label the parts of the cir-
cuit. Label points A through F and the positive and negative terminals of the
battery.
GLX Set-Up
1. Connect the voltage probe to the GLX.
a) Connect the voltage probe to the voltage port on the left side of the
GLX.
b) If there are other sensors connected to the GLX, remove them.
2. Configure the GLX for manual sampling.
a) Press to return to the Home Screen; press to open the Sensors
screen.
b) Press to open the Mode menu; press to select Manual.
The Data Properties dialog box for the manually entered resistance data
will open.
c) With Measurement Name highlighted, press ; type “r” and press
.
d) Press the down arrow key to highlight Measurement Unit. Press ,
type “ohm”, and press .
e) Press to approve these data properties and close the Data Proper-
ties window.
3. Prepare the Graph to plot voltage versus resistance.
a) Press to return to the Home Screen; press to open the Graph.
The Graph will be automatically set up for voltage versus time. In the
next step, you will select resistance (instead of time) for the horizontal
axis.
b) Press to turn on the highlight; press the down arrow key to high-
light “Time.”
c) Press to open the data source menu.
d) In the data source menu, use the arrow keys to highlight “r” and press
