Protocols below are for use with Pasco probes.

Materials:

PasPort Xplorer
PasPort conductivity sensor
PasPort conductivity probe
USB cable
DataStudio software
Standard Solution with known conductivity value

Steps for calibrating the conductivity sensor:
1. Connect the conductivity probe to the dissolved oxygen sensor by screwing it in.
2. Connect the conductivity sensor to the Pasport Xplorer device.
3. Connect the PasPort Xplorer device to the computer with the USB cable.
4. Open the DataStudio software and select “Launch DataStudio.” (or "Create an Experiment")
5. Click on the “Setup” button located near the top of the screen.
6. Click on the “Calibrate” button in the setup window.
7. Press the top button on the conductivity sensor. It should have a picture of a glass cup filled with water to the left of it.
The glass cup with water represents a sensor range of: 0 - 100 mS/cm
The flask with water represents a sensor range of 1 - 10,000 mS/cm
The ocean wave represents a sensor range of 0 - 100,000 mS/cm

8. Place the conductivity sensor probe into the first known standard solution.
9. Enter the known conductivity of the standard solution in the text box and click the “Set” button when the conductivity reading stabilizes. (Note: The known pH value and the pH reading value need not be the same.)
10. Removed the conductivity sensor probe from the standard solution and rinse with distilled water.
11. Press the "Ok" button and the sensor should be calibrated.
