6 LTC Levelogger Junior Calibration

The LTC Levelogger Junior conductivity sensor must be calibrated for reliable conductivity measurements. Calibrate the LTC Levelogger Junior for conductivity at the start of each new monitoring project or at a minimum each new monitoring season. Calibrating the LTC Levelogger Junior again directly after the monitoring project or season will provide information on the degree of conductivity deviation during the project or season. If necessary, readings can be corrected for any conductivity deviation in a spreadsheet program after the data has been exported.

The process of conductivity calibration is performed automatically by use of the Calibration Wizard. The user need only place the LTC Levelogger Junior in a specified calibration solution and follow the steps provided by the wizard. Conductivity calibration solutions are available from Solinst or any laboratory supply outlet. This LTC Levelogger Junior has an 80,000 μS/cm conductivity range and a calibrated range from 500 to 50,000 μS/cm. It can be calibrated at up to 3 calibration standard points:

1,413 µS/cm

5,000 µS/cm

12,880 µS/cm

The solution(s) must be between 10˚C and 30˚C during actual calibration. Temperature should remain stable during the 10 - 20 seconds it takes to perform each calibration.

From within the Levelogger Setting window, start the Calibration Wizard by clicking the Calibration Wizard icon . The wizard will guide you through the calibration process.

You can exit the wizard after any step to cancel the calibration session.
