Appendix B: SPARKvue HD Calibration
You can use the SPARKvue HD software if you are using the
Chemistry MultiMeasure Sensor with a PASPORT-compatible
interface connected to a computer, or with a mobile device paired
with a PASCO wireless interface, such as the AirLink2 or
SPARKlink Air.
If the sensor is connected to a PASPORT-compatible interface,
start the SPARKvue software on the computer. If the sensor is con-
nected to a SPARK SLS interface, start the interface.
For a two-point calibration of the Temperature probe, you will
need two “known standards,” such as two liquids of known tem-
perature, such as ice water and hot water. A standard thermometer
will also be needed.
After startup, the screen will show the list of measurements for the
Chemistry Sensor.
1.
Touch “Temperature” and then touch “Show”.
•
The screen will show a Graph display of temperature and
time.
2.
Touch the “Experiment Tools” icon (
) in the Graph display
screen to open the Experiment Tools menu. In the Experiment
Tools menu, touch “Calibrate Sensor”.
•
The screen will show “Calibrate Sensor: Select Measure-
ment”. The Sensor (Chemistry), Measurement (Temperature
(°C)), and Calibration Type (2 point) are already selected.
3.
Click “Next” to open the “Calibrate Sensor: Enter Values”
screen.
4.
The Calibration Point 1 “Standard Value” shows 0.0000 °C.
(This Standard Value can be changed if necessary. Highlight
the “Standard Value” and enter a new value if needed). For
this example, put the temperature probe into a “known stan-
dard” of ice water. Wait a few moments. Click “Read From
Sensor”.
5.
The Calibration Point 2 “Standard Value” shows 100.0000 °C.
For this example, put the temperature probe into a “known
standard” of hot water along with the thermometer. Wait a few
moments and read the temperature on the thermometer. High-
light the “Standard Value” and enter the temperature from the
thermometer. Next, click “Read From Sensor” and then click
“OK”.
•
The screen of the Graph display returns.
•
Follow the same procedure to calibrate pH. Use two buffer
solutions of known pH value, such as pH 4 and pH 7.
