Calibration of Sensors

When a sensor is selected, Data Pro automatically loads the standard calibration settings. Further

calibration is usually not needed.

If you choose to calibrate a sensor, tap on the Setup screen.

There are two ways to calibrate a sensor. The first is to perform a new calibration; the second is

to manually enter the calibration values. The examples shown below are for the pH sensor.

To perform a new calibration for a pH sensor, you will need two solutions with known pH

values: for example, solutions with values of 4 and 10. Follow these steps:

1. On the Setup screen, tap .

If you have more than one sensor connected, then tap the button below

Calibration, and choose which sensor you want to calibrate.

2. The current calibration will be displayed. Tap .

Note: Not all sensors can be calibrated (e.g., Stainless Steel Temperature Probe). If you select a

sensor that cannot be calibrated, Data Pro does not respond when you tap .

3. Put the pH Sensor in the pH-4 solution. Wait until the voltage number on

the screen stabilizes, enter 4 under Value, and then tap

4. Rinse and put the pH Sensor into the pH-10 solution, entering 10 instead

of 4, since you are using the pH 10 buffer. After the reading stabilizes, tap

5. Tap to return to the Setup screen.
