Troubleshooting
- Primary Test: Place the toggle switch at the desired setting, run the data-collection program, and take a reading in a solution of known TDS. We suggest using the calibration solution that comes with the probe. It is 500 mg/L TDS or 1000 microsiemens/cm (μS/cm).
- Secondary Test: If you change the setting of the toggle switch while the data collection program is running, reset the program so that the calibration equation for the new setting is selected.

Calibration
You do not have to perform a calibration for most experiments in the classroom. However, if your experimental application requires more accurate readings, you should calibrate your sensor.
