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.
