14 SETTING UP AN EXPERIMENT
CALIBRATING SENSORS
5. Touch the Calibration Type: box and select a calibration type.
See the instructions provided with your sensor for information about what
type of calibration is appropriate for your sensor.
6. Touch NEXT.
The Calibrate Sensor: Enter Values screen opens.
Now that you have selected a measurement, you can perform a calibration as
described in the next task.
Performing a calibration
After you have selected a measurement to be calibrated and a calibration type
(see previous task), you are ready to perform a calibration.
Depending on the calibration type that you have selected, perform a 2-point
calibration, a 1-point offset-only calibration, or a 1-point slope-only calibration.
Performing a 2-point calibration
In the Calibrate Sensor: Enter Values screen, complete these steps:
1. Apply a known quantity to the sensor.
For example, place a pH probe in a pH 4 buffer solution.
2. Under Calibration Point 1 touch the Standard Value: box and enter
the known value.
For example, enter the known pH of the buffer solution.
3. Under Calibration Point 1 touch Read From Sensor.
The value measured by the sensor is transferred to the Sensor Value: box.
4. Apply a different known quantity to the sensor.
For example, place the pH probe in a pH 7 buffer solution.
5. Under Calibration Point 2 touch the Standard Value: box and enter
the known value.
For example, enter the known pH of the buffer solution.
6. Under Calibration Point 2 touch Read From Sensor.
The value measured by the sensor is transferred to the Sensor Value: box.
7. Touch OK.
Calibration is complete.
