METHODS
5.5.14.3 Standby Duration
The user can enter the period of time which the cell is kept dry and ready for subsequent
analysis after a titration has finished.
The user can set the standby period up to 23 hours and 59 minutes.
5.5.14.4 Imposed Current
The HI 903 uses a bivoltametric electrode system. During a titration, the titrator monitors
the voltage required to maintain a constant polarization current (imposed current).
This option allows the user to select the electrode polarization current from the predefined list.
Note: Higher polarization currents will speed the contamination of the electrode and
potentially degrade samples.
