916 Ti-Touch
Selection 1 | 2 | 3 | 4 | off
Default value 1
off
No stirrer will be used.
Stirring rate
Setting the stirring rate. It can be set in steps of –15 to +15. The default
setting 8 corresponds to 1000 rpm. The formula for calculating the rota-
tional speed is specified in chapter 31.3, page 407. The optimum stirring
rate can be tested in the manual control.
The algebraic sign of the stirring rate changes the direction in which the
stirring is done. When the stirrer is viewed from above, this means:
￭ "+": counterclockwise rotation
￭ "–": clockwise rotation
Input range –15 - 15
Default value 8
Switch off automatically
on | off (Default value: on)
If this parameter is activated, the stirrer will be switched off automatically
at the end of the titration, measurement, etc.
28.2 Monotonic equivalence point titrations (MET)
28.2.1 Start conditions
The parameters that are carried out before the start of titration are
defined under [Start conditions]. The start conditions are processed in
the following sequence:
1. Start volume
2. Start measured value
3. Start slope
4. Pause
Start volume
Volume that is dosed prior to the start of the titration.
Input range 0.00000 - 9999.99 mL
Default value 0.00000 mL
Dosing rate
Rate at which the start volume is dosed.
Input range 0.01 - 166.00 mL/min
