TITRA
TION METHODS
5.5.21. VOLUME/FLOW RATE
The flow rate for the dosing system can be set by the user in an interval of 0.3 to two times the burette volume:
0.3 to 10 mL/min for a 5 mL burette
0.3 to 20 mL/min for a 10 mL burette
0.3 to 50 mL/min for a 25 mL burette
0.3 to 100 mL/min for a 50 mL burette
Note: The titrator will automatically detect the burette size and display the correct high limit volume.
The flow rate is set for all burette operations.
5.5.22. SIGNAL AVERAGING
Option: 1,2,3 or 4 readings
This option enables filtering on the mV/pH reading.
If 1 Reading is selected, the filtering is disabled. The titrator will take the last reading and place it into a “moving window” along with
the last 2, 3 or 4 readings (depending on the selected option). The average of those readings is displayed and used for calculations.
Averaging more readings is helpful when a noisy signal is received from the electrode.
