Salinity Calibration
22
● Salinity Calibration
Calibration is necessary for accurate salinity measurement. To perform salinity calibration
using EC2000 or PC2000 meter, follow the procedure detailed below:
Prerequisites
• Clean the conductivity electrode with DI (deionized) water and wipe it with tissue paper.
• Switch on the meter and plug in the conductivity electrode.
• Prepare salinity standard required for calibration.
• Ensure that the meter is in SAL mode.
• Dip the conductivity electrode in the salinity standard until the hole at the upper part of the
electrode is immersed.
• Before salinity calibration, set the required salinity type. The available salinity types are:
-NACL
-SEA.W (Seawater)
• The default salinity type is NACL . To set a desired salinity type, refer to “P3.2 Salinity Type
Setup” on page 50.
• User can adjust the salinity value by calibration.
To abort an ongoing calibration process at any point of time, press the key.
