Conductivity Probe (CON-BTA)
Specifications and User Guide

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.
-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 new calibration when using the Conductivity Probe for most experiments in the classroom. However, if your experimental application requires more accurate readings, you should calibrate your sensor.
-See the user manual for calibration instructions: Specifications and User Guide
