METHODS
If one of the options (V-Blank or Blank-V ) is selected in the View / Modify Method screen
the Blank Value option will became active and the value of blank can be set (in liters).
5.5.10 Imposed Current (HI 902 only)
When Fixed End Point (mV) (see 5.5.4 End Point Mode) is set, the Imposed Current
option will become available.
Using the imposed current feature in end point redox titrations has a great advantage on the
speed of the redox reactions. The speed is increased significantly when the double Pt electrode
used for the titration is polarized with a small imposed current (we obtain a stepper jump,
perfect adapted for end point titrations).
In order to use this feature you must install the HI 900401 imposed current analog board.
