parameters.
parameters and measurement progress is displayed on
this page. Before measurement, it is recommended to
check the measurement parameters. If any modification is
needed, enter the Setup-Measurement Setup menu to
modify the parameters and enter the Manual Operation-
Measurement page again after saving.
During measurement, the current operation can be
aborted by clicking "Stop". It is not recommended to use
the "Stop" function under this circumstance as pressing
"Stop" will cause the instrument to fully flush the lines and
rinse the flow cell.
Calibration
Click "Start" to implement manual calibration. Before
calibration, it is recommended to check the Calibration

calibration failure response mechanism. Default settings
are recommended to begin with. If these parameters need
to be modified, enter the Setup-Calibration Setup page to
modify the parameters and enter the Manual Operation-
Calibration interface again after saving.
During calibration, the current operation can be stopped
by clicking "Stop", but the user is not recommended to use
the "Stop" function under this circumstance.
As described above in the explanation of the Setup
menus, if calibration points is set to Double (two point

should be set to 4000 µg/L, and the corresponding standard
bottles should be used.
After the instrument calibration is finished, the instrument
will pop up a window to show calibration results. Click
"Confirm" to complete the instrument calibration.
The calibration results of the instrument will be kept in
calibration records. Users can enter the Log-Calibration
Log page to view the calibration results.
Validation
Validation is used to verify the accuracy of the instrument.
and
A validation solution with known concentration is used for
verification. 20 µg/L silica standard is often used for
validation for ultrapure water. Insert the validation tubing
into the validation solution bottle, then click the "Start"
button for validation.
When
conducting the instrument verification, it is
recommended that the validation solution shall be
purchased from official channels.
If the validation fails (based on the Threshold settings), a
new calibration is recommended. This action
