7.2
Salinity Calibration
The salinity conversion is available by con-
ductivity, yet the calibration using the stan-
dard solution of sea water can obtain an
accurate salinity concentration.
Perform the calibration in the temperature
mentioned in the standard sea water as in the
following step:
1.
Immerse the electrode in the stan-
dard sea water.
2.
In the SALT Measurement screen,
press the CAL key.
The SALT CALIBRATION screen
appears.
3.
Press
↑
or
↓
key to set the con-
centration of standard solution
used for the calibration.
Setting range: 0.00 to 5.00%
4.
Press the CAL key.
The calibration starts.
When the calibration is completed, the
selected Salt Calibration Coefficient is
set.
5.
Press the MEAS key to return to
the Measurement screen.
