When reading stable, you can press ‘ENTER’ key, meter automatically calculates new TDS
factor, calibration finishes. Press ‘CANCEL’, meter stops the calibration of TDS factor.
4.9.5. Salinity Measurement
Before measure salinity, you must refer to the chapter Selection of Conductive Electrode to
confirm the conductive electrode to be used in measurement, setup suitable cell constant. Under
starting state, if you have already selected conductive measurement mode parameter, such as
conductivity parameter, you can start measurement directly. Otherwise, you should enter into
‘Setup Measurement Mode’
, select conductive measurement unit to measure. (
Please refer to
‘Set Measurement Mode’ for details
).
For the display, measurement procedure and operating, please refer to chapter Conductivity
Measurement.
