How do I manually calibrate my Go Wireless pH or EA in Graphical Analysis GW for iPad or Android? How do I manually calibrate my sensor in LabQuest App? How do I manually calibrate my sensor in Graphical Analysis and Graphical Analysis Pro? Select Calibrate from the Experiment menu.Ĭalibration in Other Data-Collection Programs:.Note, however, that the factory calibration may no longer be a useful calibration if the sensor is not new. You can reset the sensor to its factory calibration by following these steps. If you wish to use the calibration only for the current experiment, proceed to Step 10. Once stored, this new calibration will be used automatically, regardless of the interface to which the sensor is connected. (Optional) If you wish to store the calibration on the sensor itself, go to the Calibration Storage tab.
When the displayed voltage reading stabilizes, click Keep. In the calibration dialog box, you will see the potential output of the sensor in volts. Place the sensor in a known environment (e.g., atmospheric pressure if calibrating a pressure sensor).Choose Calibrate from the Experiment menu and check the One Point Calibration box if it is not already checked.Click Done to complete the calibration process.Pressing ‘Write’ will apply your changes to the sensor.” Click Write. Configuration data stored on the sensor will be lost. You will be prompted by the message, “Warning: You are about to change information in your sensor. Make sure the Default Page corresponds to your new calibration. If you wish to use the calibration only for the current experiment, proceed to Step 11. When the voltage reading stabilizes, click Keep. Enter the second known calibration value in the edit box.If using a wet sensor, rinse the sensor with distilled water and place it in the second standard solution. Move the sensor to the second set of known conditions.Type in the first known calibration value in the edit box.If using a wet sensor, remove the storage bottle from the sensor (if applicable), rinse the tip of the sensor with distilled water, and place the sensor in the first standard solution so the tip is immersed.
Place the sensor in the first known set of conditions (e.g., known suspended mass or known pH buffer).Choose Calibrate from the Experiment menu and then click the Calibrate Now button.The program will identify the sensor and load a default data-collection setup.
