SALINITY CALIBRATION SALINITY CALIBRATION SALINITY CALIBRATION SALINITY CALIBRATION SALINITY CALIBRATION
Salinity calibration is a one-point procedure at 100.0% NaCl. Use the HI 7037L calibration solution
(sea water solution) as a 100% NaCl standard solution.
To enter salinity calibration:
• Set the meter for salinity range;
• Select the
Percent Scale (see Salinity Setup section);
• Rinse the probe with some of the calibration solution or deionized water;
• Immerse the probe into HI 7037L solution. The sleeve holes must be completely submerged. Tap
the probe repeatedly to remove any air bubbles that may be trapped inside the sleeve.
• Enter in calibration mode by pressing ;
• Wait to stabilize;
• Press
to finish salinity calibration or press to cancel calibration.
