Sets the speed of the burette used for dosing the increments during a
Monotonic IP or Dynamic IP titration.
When carrying out titrations where the reaction is very slow, decrease
the speed value. For titrations in non aqueous media, where a deposit
is created, the speed can also be decreased.
Enter in:
Method parameters menu (Monotonic IP or Dynamic IP).
Range available:
0.01 ml/min to 50 ml/min.
The maximum speed of a burette is the nominal volume
dispensed in 20 s (for 1 ml, 2 ml, 5 ml, 10 ml and 20 ml burettes)
and in 40 s (for 50 ml burette). In the example of a 10 ml burette,
it means that the speed will stay at 30 ml/min if a value is
entered within the range 30 ml/min - 50 ml/min.
The stability criterion is used to control the stability of the electrode
signal. Selecting a low value will bring about, accurate but long
measurements.
Enter a stability which is close to the default value (50 mpH/min,
3.0 mV/min or 1.0 %/min).
A zero stability criteria will have no effect on the stability test
performed, the reading will be taken into account when the
Acceptation time is exceeded.
Enter in:
Edit method > Parameters menu
Edit electrode > Calibration parameters menu
Range available:
0 to 99 mpH/min or 0 to 99.9 mV/min or 0 to 99.9 %/min
