Group Parameter Description
Zeta
Measurement
(Details) Polarity Select the polarity of the applied voltage from
positive, negative, or automatic on the reference
electrode. Select
Auto if you aren’t sure what to use.
Select Voltage (V) Displays when you select Fixed as the Applied
Voltage so that you can enter a desired voltage. The
DC voltage range is 0 - 300 V.
Titrator Titration Mode This parameter determines the mode for pH titration
vs. size, diluting/priming, or circulation of the
sample.
Choose pH titration , Pipetting , or Circulation .
The Titration Mode is applicable only when using a
flow cell.
pH Titration
Displays when
pH titration is
selected.
pH Table The pH values can be entered from low to high or
from high to low. Set the pH value to be adjusted. The
pH range is 1 - 13.
pH Tolerance The pH value is considered to have been completed if
the pH is in the specified range (the pH setting ± the
tolerance value). Set the tolerance value for the pH
adjustment. It ranges from 0.05 - 2.
Additive
Titration
Displays when
Pipetting is
selected.
Circulation Time
(min) Set the time for the sample to circulate around the
flow cell after adding the additive. The range is

1 - 999 minutes.
Titration Volume
Table Set the volume of the additive. The range is

1 - 50,000

L.
Circulation
Volume
Displays when
Circulation is
selected.
Circulation Time
Table Sets the time for the sample to circulate around the
flow cell. The range is 1 - 999 minutes.
