Appendix B: Calibration
Calibration is not always necessary, especially if you are
measuring a change in temperature rather than absolute
temperature values. However, it is possible to calibrate
the sensor.
Prepare for Calibration
Calibration will need an ice-water bath, a container of
hot water, and a thermometer. The sensor will need to
be “paired” with a tablet or computer, and the data
collection software (for example, SPARKvue or
Capstone) should be running.
Using SPARKvue Software for Calibration
NOTE: Check the Help System in SPARKvue for the
most up-to-date information.
1. Place the thermometer in the container of hot water.
2. Click (or press) the Experiment Tools button ( ).
•
The Experiment Tools screen opens.
3. Click Calibrate Sensor.
•
The Calibrate Sensor: Select Measurement screen
opens.
4. Click the Sensor box and click the sensor to be
calibrated.
5. Click the Calibration Type box and click a calibration
type. (For this example, click “2-point”.)
6. Click Next.
•
The Calibrate Sensor Enter Values screen opens.
7. Place the temperature probe in the container of hot
water.
8. Read the temperature on the thermometer. Under
Calibration Point 1, click the Standard Value box
and enter the known temperature value.
9. Under Calibration Point 1, click Read From Sensor.
•
The value measured by the sensor is transferred to
the Sensor Value box.
10. Move the thermometer to the ice-water bath. Dry the
temperature probe and then put the probe into the
ice-water bath with the thermometer.
11. Wait until the reading on the thermometer stabilizes.
Under Calibration Point 2, click the Standard Value
box and enter the thermometer’s temperature value.
12. Under Calibration Point 2, click the Read From
Sensor box.
•
The second value measured by the sensor is
transferred to the Sensor Value box.
13. Click OK.
Using PASCO Capstone for Calibration
NOTE: Check the Help System in PASCO Capstone for
the most up-to-date information.
1. Place the thermometer in the container of hot water.
2. Click Calibration ( ) in the Tools Palette.
3. Choose the measurement you would like to calibrate
now: Temperature Measurement.
4. Click Next.
5. Choose the type of calibration you would like to
perform: Two Standards (2 point).
6. Click Next.
7. Read the temperature on the thermometer and enter
the value in the Standard Value text box.
8. Place the Temperature Probe in the container of hot
water.
9. After the Current Value stabilizes, lick Set Current
Value to Standard Value.
10. Click Next.
11. Move the thermometer to the ice-water bath. Dry the
end of the temperature probe. Place the probe in the
ice-water bath with the thermometer,
12. Wait until the reading on the thermometer stabilizes.
Enter the second known temperature value in the
Standard Value text box.
13. After the Current Value stabilizes, click Set Current
Value to Standard Value.
14. Click Next.
15. Click Finish.
