Appendix A: DataStudio Calibration
In DataStudio, click the Setup button to open the Experiment Setup window; in that
window, click the Calibrate button to open the Calibrate Sensors dialog box. For a
two-point calibration, you will need two “known standards,” such as two buffer solu-
tions of known pH or two liquids of known temperature.
1. From the Sensor field, select Chemistry.
2. From the Measurement field, select Temperature or pH.
3. Ensure that “Calibrate all similar measurements simulta-
neously” is not selected.
4. From the Calibration Type menu, select 2 Point (Adjust Slope
and Offset), if it is not already selected.
5. Place the temperature or pH probe in the first known standard.
6. Enter the known temperature or pH of the standard in the
Standard Value field for Point 1.
7. Observe the Present Sensor Measurement and wait until it
has stabilized.
8. Click the Read From Sensor button for Point 1.
9. Place the probe in the second known standard.
10. Enter the known temperature or pH of the standard in the
Standard Value field for Point 2.
11. Observe the Present Sensor Measurement and wait until it
has stabilized.
12. Click the Read From Sensor button for Point 2.
13. Click OK to accept the new calibration.
Appendix B: EZ Screen
If you are using the Chemistry MultiMeasure Sensor with a PASPORT interface con-
nected to a computer, you can use EZ-Screen software instead of DataStudio. When
the sensor is connected to the computer through the interface (if DataStudio is not
running) a window automatically launches giving you the option of launching
EZ-Screen. In EZ-Screen, click the green arrow button to start data collection. Click
the Chemistry Sensor icon in the lower-right corner to cycle through the measure-
ments and units.
