Sipper module
Automatic Mode
The characteristics of the three basic sipper cycles can be defined in the automatic mode:
Sip Time, Settle Time, and Purge Time.
• Sip Time: The sip time and the pump setting determine the sample volume that can
be pumped into the cell.
• Settle Time: The settle time is the interval that must be allowed before the
measurement is performed. During this time, air bubbles that may have formed during
pumping can be eliminated, and any turbulence in the sample can settle.
• Purge Time: The purge time determines the volume of air or purging solution that is
pumped through the cell after the measurement.
Note: If the Sipper Module is not in automatic mode, press the PURGE START: MANUAL key to
change the mode to Auto.
Press ZERO or READ to run the programs through the sipper cycles automatically. Press
READ to run the program through the Sipper Module.
Manual Mode
In the manual Sipper mode, the purge cycles can be activated manually. This mode can
be useful during the input of the basic parameters, as an aid to determining which
parameter values to work with in the automatic mode.
