Salinity · Select the "Salinity" option and press <OK>. · Insert the salinity value of the custom calibration solution. · Immerse the probe in the solution and wait for stable reading. · When the reading is stable, press <Confirm> to store the calibration data. · After confirmation, the following messages are displayed: "Storing data on probe, please wait. . . ", "Updating GLP data, please wait. . . " and "Calibration completed". · Press <OK> to return to the "Calibration" menu. · To return to the main menu, press ESC repeatedly. Notes These procedures calibrate the slope value. To calibrate the offset, set the calibration point at 0 S/cm and repeat the procedure. If the temperature input is not within the acceptable range (0 to 50°C), the message "Invalid temperature" is displayed. If the conductivity input is not within the acceptable range, the message "Invalid input" is displayed. · To change the standard value, press <Cal. point> and the list of available standard values is displayed: 0 S/cm, 84 S/cm, 1413 S/cm, 5. 00 mS/cm, 12. 88 mS/cm, 80. 0 mS/cm and 111. 8 mS/cm. · Press <Custom> to insert a custom value (temperature compensated value). Choose <Resolution> to select the desired resolution. · When the reading is stable, press <Confirm> to store the calibration data. · After confirmation, the following messages are displayed: "Storing data on probe, please wait. . .
