pH+Sensor+Probe

This page is to give directions on the basics of how to use the pH Sensor Probe.
 * Steps on Using the ph Sensor Probe **


 * Step 1: Plugging into the Probe.** Plug the probe into the LabQuest. You plug it into the channel spots at the top of the LabQuest.


 * Step 2: Taking the pH Sensor out of its solution.** Twist the solution off of the pH Sensor. ** DO NOT PULL! ** It is very sensitive.


 * Step 3: Turning on the LabQuest.** Turn on the LabQuest. To start it you first must press the small silver button in the upper left corner of the LabQuest. You have to press it kind of hard, especially when you turn it off. The opening screen will show that the sensor is plugged by starting to read the solution that the pH Sensor is in.

 * Step 4: How to use the probe.** Stick the probe into a liquid to test. Just hold it in the liquid, or attach it to a stand. The LabQuest or Logger Lite computer software should start immediately picking up data. (Look at the end on how to attach the pH Sensor to the computer to use Logger Lite.)


 * Step 5: Start collecting data.** When you want to start collecting data, press the play button on the LabQuest or on the LabQuest Screen with the stylus pen.

 * Step 6: Tab buttons.** Press the tab buttons on the top of the screen to switch to different screens. To do this, use the stylus pen that is in the back of the LabQuest. The best (In my opinion) and most useful features of LabQuest and Logger Lite is that it records data in real time. You can watch a graph change or the table of data change instantaneously.

 * Step 7: Stop recording.** When you are done recording your data, you need to press the play button on the LabQuest, or the stop button on the screen to stop recording data.


 * Step 8: Saving Data.** If you want to save your data, click on the file tab at the top of each screen and scroll down to save. Then you use the keyboard that pops up to give it a file name.

 * Step 9: Putting the pH Sensor away.** When you are done with the pH Sensor, rinse it off with water and dry it carefully. Avoid touching the sphere at the end of the probe for it is very delicate. Twist the probe back into the solution.


 * Here is a video to show you how is works as well!**
