7.3.9 Titrant Concentration Parameter
When mode is generated, the parameter is usually set to BLANK and user should input this
parameter when calculating concentration value (see 8.1.3 ‘Sample Concentration).
7.4 Blank Titration Mode
This mode is suitable for the titration that demands less titrant (below 1ml). In this mode, every
time the meter adds 0.02 ml of volume (users can amend this parameter), users can also set pre-
added volume parameter so as to make titration speed higher. Thus the meter will automatically
search for titration end point to generate special titration mode. When the volume is small in
titration, user can select blank titration. In starting status, press ‘Titration’ button, select ‘Blank
Titration’ to enter into blank titration mode, displayed as follows:

Pre-adding Volume: 0.5mL
Each Adding: 0.02mL
