Conductivity Sensor 012–06485B
➤ Always calibrate the
electrode before measuring
absolute (rather than relative)
concentrations.
Single-Point Calibration
1. Open the Conductivity Sensor calibration dialog box by double-
clicking the Conductivity Sensor icon in the Experiment Setup
window.
2. Make sure that the low value is set at 0.000 µS/cm and 0.000 volts
(default values). If these values are not set at zero, enter 0.000 in
the dialog boxes for Low Value of µS/cm and Volts.
3. Place the Conductivity Sensor into the calibration solution. In the
High Value box type a value in µS/cm that corresponds to the
known weight percent solution. As soon as the voltage reading
stabilizes, click Read to enter the HighValue.
