Direct-Connect Temperature Probe (TC1101)

The Connections:

1. Connect the Direct-Connect Temperature Probe to Port 1 of the Serial Box Interface.

2. Connect the Serial Box Interface to the COM I or COM2 port of the computer using the cable provided. (Use the 9-pin to 25-pin adapter if necessary.)

3. Plug the Serial Box Interface into an electrical outlet using the AC adapter.

The Set-up/Customizing Data Logger:

1. Open the Data Logger program. Click on Start, Program, Vernier, Logger Pro.

Note: If a message box reading “Warning! Cannot find the interface box” appears:

a) Check all connections,

b) Determine which port (COM1 or COM2) is accepting the cable from the Serial Box Interface, and

c) Click on the appropriate button (“COM1” or “COM2”).

A default graph call untitled- 1” will appear.

The right mouse button Is used only to access Data logger menus. Use the left mouse button for all other operations.

2. Under the “File” menu, choose “Open... ”. A new window will appear, listing the various experiment files for Data Logger.

3. From the list, double-click on “Temperature Probes” choose “Direct Connect Temperature Probe” to open the file for the direct temperature measurements. You may need to scroll the list by clicking on the left mouse button and dragging the cursor across the list to find these files.

5. The “Setup” menu can be used to specify

Sensor [Sensor setup, Calibration, and Details(units can be specified here)]

Data Collection [Mode, Sampling (Rate)]

and Interface details (Com port).

6. You do not need to customize the axes for the introductory activity. However, if you would like to customize the axis:

a) Double-click anywhere on the graph. This cases the “Axes” dialog box to appear.

b) Click and hold the cursor on the y-axis label (which currently reads

“Temp 1 & Temp 2”). Move the cursor to “Temperature 1” to collect data using Port 1 only. If you are using temperature probes in both ports, you do not have to do this.

c) To change the y-axis temperature range, simply Double-click inside the upper and/or lower limit value box and enter the desired value.

d) The x-axis should already be in units of “Time.” You may change the values in the upper and/or lower limit value boxes in the same manner as you did for the y-axis above.

You are now ready to collect data. Simply click “Collect” when you are ready to begin; click “Stop” to discontinue data collection.

Introductory Activity: Calibration:

1. Open the “Direct Connect Temperature probe” file and load the calibration file, as described above.

2. Prepare a water bath by adding 300 ml of water to Dewar.

3. Place the Standard Temperature Probe in the water bath.

4. Click on ”Collect”.

5. Click “Stop” to discontinue data collection.

6. Heat a water bath to boiling!

7. Place the Standard Temperature Probe in the water bath.

8. Click on ”Collect”.

9. Use Calibration in the “Experiment” menu to calibrate the sensor using the water baths at 0 °C and 100 °C.
