Make sure that the sample bottle fits snugly over the rubber stopper; only an airtight seal will pump the sample water into the conductivity cell.
When the Autosal is not in use, a sample bottle of distilled water should be attached and the conductivity cell filled with distilled water. See Finishing a Run for more information on this process.
The function switch should be set at "Standby" when not in use.
Once the pumps are turned on for a run, keep them on until the run is complete.
For more detailed instructions for the instrument, please refer to the Guildline manuals located on the shelf just below and to the right of the Autosal instruments.
Starting the Autosal Process
Before running salts, make sure to have all the equipment you need:
two seawater standard vials (at room temperature) from the same batch
samples (at room temperature)
an ample supply of kimwipes
latex gloves
file for removing glass tops of standardized seawater
log sheets
bucket to catch outflow
supply of distilled water
Read the zero value of the instrument by turning the function switch to Zero. Ensure that the display reads between 0.0 0000 and 0.00005. The closer the value is to zero, the better. If 0.00005 can't be reached, contact the MST on board for assistance.
Standardizing the Autosal
Before and after a run of salts (usually 48 samples), the Autosal should be standardized in order to obtain accurate data. This is done by running a standardized seawater sample and standardizing the reading to twice the K15 value printed on the seawater sample.
When the instrument has been stored with distilled water in the cell, the cell should be flushed with some seawater (either an open standard or an old sample bottle) before standardizing in order to prime the cell. Flush the cell approximately 10 times before placing the standard on the instrument. See directions below for flushing the cell.
